PERM Recruitment: Why Your Employer Posted Your Job and Is Interviewing US Applicants
Your green card requires your employer to advertise your job and reject every US applicant for a lawful, documented reason. Here is what the law actually demands, and why you cannot be in the room.

You opened the company careers page and there it is: your title, your team, most of your job description, posted publicly. Or you walked past the break-room noticeboard and saw a printed notice with your salary on it. Or a colleague mentioned they are interviewing someone for a role that sounds exactly like yours.
You are not being replaced. This is your green card case. What you are looking at has a name — PERM labor certification recruitment — and every element of it is prescribed by federal regulation at 20 CFR part 656, not invented by your employer. The advertising is not a search for your replacement. It is evidence your employer has to produce before the Department of Labor will certify your case at all.
Two things have to be said before anything else, because leaving either out would be dishonest.
⚠️ The honest part. PERM is a test of the US labour market, and it is built to be capable of failing. Under 20 CFR 656.24(b)(2), the Certifying Officer decides your case on the basis of whether "there is in the United States a worker who is able, willing, qualified, and available for and at the place of the job opportunity." If there is, the certification is denied. Your employer cannot lawfully manufacture a rejection to keep your case moving. Most campaigns do not produce such a candidate. Some do. Anyone telling you this is a formality is not telling you the truth.
⚠️ Stay out of it. Under 20 CFR 656.10(b)(2)(i), you may not interview or consider US workers for the job offered to you. Neither may your own attorney. Offering to review resumes, sit in on a screen, or advise your manager on candidates is not helpfulness. It is a documented problem in a file DOL can audit for the next five years.
What PERM recruitment is actually for
The legal purpose sits in the statute. Per 20 CFR 656.1, which restates INA 212(a)(5)(A), certain foreign nationals cannot obtain immigrant visas for permanent employment unless the Secretary of Labor first certifies two things:
- There are not sufficient US workers who are able, willing, qualified and available at the time of application and at the place where the work will be performed; and
- Employing you will not adversely affect the wages and working conditions of similarly employed US workers.
The recruitment campaign is how the employer builds the record for point one. The prevailing wage determination is how it handles point two.
Where this sits in the sequence: your employer obtains a prevailing wage determination from DOL's National Prevailing Wage Center, runs the recruitment, files Form ETA-9089, and only after certification files the I-140 with USCIS. The full PERM-to-green-card sequence covers the whole arc. This article is about the middle part, the part that is happening in front of you.
One structural fact to hold onto now: DOL states that "the date the labor certification application is received by the DOL is known as the filing date and is used by USCIS and the Department of State as the priority date." 8 CFR 204.5(d) says the same from the USCIS side. Not the certification date. Not the I-140 date. The day the application lands. Which is why the recruitment calendar is not just bureaucracy — it is the thing standing between you and your place in the queue.
The recruitment your employer must run, step by step
For a professional occupation, the regulation splits recruitment into two mandatory steps and three of your employer's choosing. All of it must fall inside a six-month window before filing.
| Requirement | Rule | Timing |
|---|---|---|
| SWA job order, 30 days | 656.17(e)(1)(i)(A) | At least 30, no more than 180 days before filing |
| Two Sunday newspaper ads | 656.17(e)(1)(i)(B) | At least 30, no more than 180 days before filing |
| Three additional steps from (A)–(J) | 656.17(e)(1)(ii) | None older than 180 days; only one may fall solely within 30 days of filing |
| Notice of Filing posted 10 consecutive business days | 656.10(d) | Provided between 30 and 180 days before filing |
| Recruitment report, signed | 656.17(g)(1) | Prepared before filing, produced on audit |
| Retain everything | 656.10(f) | 5 years from the filing date |
Whether the job counts as "professional" is not a judgment call your employer makes freely. DOL publishes PERM Appendix A, described on its permanent labor certification page as a list of professional occupations that guides employers in complying with the professional recruitment requirements at 656.17(e)(1).
The two mandatory steps
The job order. Placement of a job order with the State Workforce Agency serving the area of intended employment for a period of 30 days. The regulation makes the documentation trivially simple: "The start and end dates of the job order entered on the application shall serve as documentation of this step."
Two Sunday advertisements. An advertisement "on two different Sundays in the newspaper of general circulation in the area of intended employment most appropriate to the occupation and the workers likely to apply for the job opportunity and most likely to bring responses from able, willing, qualified, and available U.S. workers."
Two variations exist. If the job is in a rural area with no Sunday edition, the employer may use the edition with the widest circulation. And where the job requires experience and an advanced degree and a professional journal would normally be used, the employer may replace one of the two Sunday ads with an advertisement in "the professional journal most likely to bring responses."
The ads themselves are constrained by 656.17(f). They must name the employer, direct applicants to the employer, describe the vacancy specifically enough to apprise US workers of the opportunity, indicate the geographic area with enough specificity to convey travel requirements, and — three things worth noticing — must not contain a wage rate lower than the prevailing wage, must not contain requirements or duties exceeding those on the ETA-9089, and must not contain terms less favourable than those offered to you.
The three additional steps
The employer picks three from a closed list of ten at 656.17(e)(1)(ii). Here is the complete set, straight from the regulation:
- (A) Job fairs
- (B) The employer's own website
- (C) A job search website other than the employer's
- (D) On-campus recruiting
- (E) Trade or professional organisations
- (F) Private employment firms or placement agencies
- (G) An employee referral programme with incentives
- (H) Campus placement offices
- (I) Local and ethnic newspapers
- (J) Radio and television advertisements
Each has its own documentation requirement written into the regulation — dated web pages, brochures naming the employer as a job-fair participant, contracts with the placement agency, a written confirmation from the radio station stating when the ad aired. Two timing rules apply on top: only one of the three may consist solely of activity within 30 days of filing, and none may have taken place more than 180 days before filing.
If you have been watching your job appear on three different job boards over two months and wondering why, this is why. It is a checklist being worked through.
The Notice of Filing at your workplace
The posted notice is required by 656.10(d). If there is a bargaining representative for the occupational classification, notice goes to them. If there is not, then:
"by posted notice to the employer's employees at the facility or location of the employment. The notice must be posted for at least 10 consecutive business days. The notice must be clearly visible and unobstructed while posted and must be posted in conspicuous places where the employer's U.S. workers can readily read the posted notice on their way to or from their place of employment."
Ten consecutive business days, not calendar days. The regulation even suggests where: "in the immediate vicinity of the wage and hour notices required by 29 CFR 516.4 or occupational safety and health notices required by 29 CFR 1903.2(a)." And it must also be published "in any and all in-house media, whether electronic or printed" used for recruiting similar positions, which is why it sometimes lands in a company Slack channel or intranet post as well as on the wall.
Content requirements, from 656.10(d)(3) and (d)(4). The notice must:
- State that it is provided as a result of the filing of an application for permanent alien labor certification;
- State that any person may provide documentary evidence bearing on the application to the DOL Certifying Officer;
- Provide that Certifying Officer's address;
- Contain the information required for advertisements by 656.17(f);
- State the rate of pay, which must equal or exceed the prevailing wage entered by the SWA; and
- Be provided between 30 and 180 days before filing.
That "any person may provide documentary evidence" clause is not decoration. 656.10(e) gives any person the right to submit documentary evidence to the Certifying Officer, including information on available workers, wages and working conditions, and the CO "must consider this information" in making the determination.
Why your salary is on the wall
Because the regulation says it has to be. The rate of pay is a mandatory element of the Notice of Filing under 656.10(d)(4), and it must equal or exceed the prevailing wage.
This is genuinely uncomfortable and almost nobody acknowledges it: your compensation is posted in a break room where the colleagues you eat lunch with can read it. It is not an oversight, and it is not a disclosure your employer chose to make. If it helps at all, the number posted is the offered wage tied to a prevailing wage determination at a specific level, which is a narrower thing than your total compensation. How the prevailing wage level is set explains where that figure comes from.
The 30-day quiet period and the 180-day ceiling
Three different rules use the number 30, and conflating them produces a wrong timeline.
- The SWA job order runs for 30 days — that is a duration.
- The mandatory steps must be completed at least 30 days before filing — that is a floor.
- Only one of the three additional steps may consist solely of activity within 30 days of filing — that is a constraint on freshness.
Plus the Notice of Filing has its own window: provided between 30 and 180 days before filing.
The 30-day floor is what people call the quiet period. Its function is straightforward: anyone who responded to the advertising must have a real opportunity to be considered before the employer signs an application certifying to DOL that no able, willing, qualified and available US worker was found. A campaign that closes on Monday and files on Tuesday would make that certification meaningless.
The 180-day ceiling works the other way. Recruitment goes stale. If your employer's earliest recruitment step ages past 180 days before the application is filed, that step no longer counts, and depending on which one it was, the campaign may have to be run again from the top. This is one of the most common reasons a case slips by months, and it is worth knowing that the delay is usually calendar mechanics rather than a signal about you.
Set expectations accordingly: from the start of recruitment to filing is realistically months, not weeks, before DOL has even looked at the case.
What happens when someone applies
The recruitment report
656.17(g)(1) is where the whole campaign gets reduced to a defensible record:
"The employer must prepare a recruitment report signed by the employer or the employer's representative noted in § 656.10(b)(2)(ii) describing the recruitment steps undertaken and the results achieved, the number of hires, and, if applicable, the number of U.S. workers rejected, categorized by the lawful job related reasons for such rejections. The Certifying Officer, after reviewing the employer's recruitment report, may request the U.S. workers' resumes or applications, sorted by the reasons the workers were rejected."
Read that last sentence again. The CO can demand the resumes, sorted by rejection reason. A recruitment report with a vague category like "not a fit" is an invitation to have that examined.
The employer also attests, on the application itself and per 656.10(c), under penalty of perjury under 18 U.S.C. 1621(2), to a list of conditions including that "the job opportunity has been and is clearly open to any U.S. worker" and that "the U.S. workers who applied for the job opportunity were rejected for lawful job-related reasons." Failure to attest to any condition results in denial.
What counts as a lawful rejection
656.17(g)(2) deserves to be read in full, because it is the sentence that decides most contested cases:
"A U.S. worker is able and qualified for the job opportunity if the worker can acquire the skills necessary to perform the duties involved in the occupation during a reasonable period of on-the-job training. Rejecting U.S. workers for lacking skills necessary to perform the duties involved in the occupation, where the U.S. workers are capable of acquiring the skills during a reasonable period of on-the-job training is not a lawful job-related reason for rejection of the U.S. workers."
The Certifying Officer applies the same standard directly under 656.24(b)(2)(i): a US worker is able and qualified if, "by education, training, experience, or a combination thereof," they can perform the duties in the normally accepted manner, and again if they can acquire the necessary skills in a reasonable period of on-the-job training.
The requirements themselves are also policed. Under 656.17(h)(1), the job's requirements "must be those normally required for the occupation and must not exceed the Specific Vocational Preparation level assigned to the occupation as shown in the O*NET Job Zones" unless documented as arising from business necessity — and business necessity requires showing the duties and requirements "bear a reasonable relationship to the occupation in the context of the employer's business and are essential to perform the job in a reasonable manner." A foreign-language requirement is separately barred under 656.17(h)(2) unless justified, which gives a sense of how tightly this is scrutinised.
And 656.17(i), the actual-minimum-requirements rule, closes the obvious loophole. The stated requirements "must represent the employer's actual minimum requirements," the employer must not have hired people with less training or experience for substantially comparable jobs, and where the beneficiary already works there, DOL reviews what you had at the time you were hired. The employer generally "can not require domestic worker applicants to possess training and/or experience beyond what the alien possessed at the time of hire."
The point of walking through all of this is not to arm anyone. It is so you understand that the posting you are looking at is a real job opportunity that has to be genuinely available, and that the requirements in it are constrained. Nobody can quietly write the ad so that only you can answer it.
If a qualified US worker is found
State it plainly: the Certifying Officer denies the certification. Your employer is not permitted to invent a reason.
What usually happens next is a conversation between your employer and its immigration counsel about whether the role can be restructured, filed at a different level, or filed for a different location — and that is a decision for the employer and its lawyers, not a strategy for you to propose or execute. It also cannot be handled by tidying the file after the fact: 656.10(f) requires the employer to retain the application and all supporting documentation for five years from the filing date. If the employer wants to contest a denial, 656.24(e) provides 30 days from the determination to request review, and missing that window makes the denial final. That is counsel's territory.
Why you cannot be involved, in any capacity
This gets its own section because the instinct to help is so strong and so costly. 656.10(b)(2)(i):
"It is contrary to the best interests of U.S. workers to have the alien and/or agents or attorneys for either the employer or the alien participate in interviewing or considering U.S. workers for the job offered the alien. As the beneficiary of a labor certification application, the alien can not represent the best interests of U.S. workers in the job opportunity. The alien's agent and/or attorney can not represent the alien effectively and at the same time truly be seeking U.S. workers for the job opportunity."
Note the scope. It covers you and agents or attorneys for either side. The single exception, at 656.10(b)(2)(ii), is narrow: the employer's representative who interviews or considers US workers "must be the person who normally interviews or considers, on behalf of the employer, applicants for job opportunities such as that offered the alien, but which do not involve labor certifications."
So "our company's immigration lawyer is handling the screening" is not a safe answer unless that person is genuinely the employer's normal screener for comparable non-PERM roles, which they almost never are.
The hiring-manager conflict
The version of this that catches senior readers: you are the person who normally screens candidates for this role, and the role is yours. That is a real conflict under 656.10(b)(2), and it has to be resolved by your employer and its counsel before recruitment starts, not improvised when the first resume lands in your inbox. Raise it early, in writing, through the right channel, and then step back.
What you can legitimately do
You are not powerless. You are just not a participant in the screening.
- Know that your priority date will be the filing date, and what that means for your place in the queue.
- Keep dated copies of the Notice of Filing and any postings you see, plus your own file of I-797s, pay records, job description, and degree and experience documentation.
- Ask about the timeline through the proper channel — HR or the employer's counsel — rather than inserting yourself into the recruitment.
- Expect long silences, so a quiet quarter does not read as bad news.
- If you are weighing another offer mid-process, read the trade-off if you are thinking about leaving mid-process, ideally alongside your own attorney.
If you believe the recruitment is being handled improperly, or you are being asked to participate in screening, you need your own immigration attorney, not the company's. This surprises people, so it is worth saying flatly: your employer's immigration counsel represents the employer. Their client is the company, not you.
If DOL audits
Audits are routine, not an accusation. Under 20 CFR 656.20, review of an application may lead to an audit, and "certain applications may be selected randomly for audit and quality control purposes."
If selected, the Certifying Officer issues an audit letter that states what documentation the employer must submit and gives 30 days from the date of the letter to produce it. The CO may grant one discretionary extension of up to 30 more days. Failure to provide the documentation in time constitutes a refusal to exhaust administrative remedies, the case is denied, and administrative-judicial review under 656.26 is not available. A substantial failure can also result in the employer being required to conduct supervised recruitment under 656.21 on future filings for up to two years.
What gets produced is the recruitment file and the recruitment report. That is the entire reason the file is built the way it is.
On duration: check the numbers yourself rather than trusting a figure in a blog post, including this one. As of DOL's posting dated 17 July 2026 on flag.dol.gov/processingtimes, OFLC was adjudicating cases in the Analyst Review queue with priority dates of July 2025, cases in Audit Review with priority dates of December 2025, and reconsideration requests appealed in March 2026. For determinations issued in June 2026, DOL reported an average of 403 calendar days for analyst review and 290 calendar days for audit review. DOL notes actual times vary with the facts of each case, and the page updates monthly.
We are deliberately not repeating a percentage of cases audited. OFLC does not publish a current audit-selection rate on its performance pages, so any figure you see quoted should be treated as unverified. For the mechanics of surviving one, see what happens if DOL audits the case.
Where this sits in your green card timeline
The order, briefly:
- Prevailing wage determination from the National Prevailing Wage Center. Required before the PERM application can be filed.
- Recruitment and the Notice of Filing, inside the 30-to-180-day windows.
- Form ETA-9089 filed with DOL, online through the Foreign Labor Application Gateway after the employer registers via Login.gov, with mailed applications still permitted as an alternative. This filing date is your priority date.
- Analyst review, and possibly an audit.
- Certification. It has a 180-day shelf life: DOL states the certification "expires if not submitted to USCIS within this period," and 20 CFR 656.30(b) sets the same 180 calendar days. USCIS will only accept the signed version of the Final Determination form issued electronically by OFLC.
- I-140 filed with USCIS. What the I-140 stage looks like once certification is approved picks up from there, and whether EB-2 or EB-3 is actually faster for you is worth reading before the category is locked in.
A long silence during recruitment is normal. So is a long silence during analyst review. Neither is information about you.
Frequently asked questions
Why is my employer advertising the job I already have?
Because PERM labor certification requires it. Under 20 CFR 656.1, the Secretary of Labor can only certify your case after determining there are not sufficient US workers who are able, willing, qualified and available, and that employing you will not adversely affect the wages and working conditions of similarly employed US workers. To support that, 20 CFR 656.17(e) requires the employer to attest to having conducted a prescribed recruitment campaign before filing. The advertisement is not a signal that you are being replaced. It is a mandatory step in your own green card case, and the case cannot proceed without documented proof it happened.
What recruitment is my employer actually required to run?
For a professional occupation, two steps are mandatory under 20 CFR 656.17(e)(1)(i) — a job order placed with the State Workforce Agency serving the area of intended employment for 30 days, and advertisements on two different Sundays in the newspaper of general circulation in that area most appropriate to the occupation. Both must be conducted at least 30 days but no more than 180 days before filing. The employer must also select three additional steps from the ten listed at 20 CFR 656.17(e)(1)(ii)(A) through (J), which are job fairs, the employer's own website, a job search website other than the employer's, on-campus recruiting, trade or professional organisations, private employment firms, an employee referral programme with incentives, campus placement offices, local and ethnic newspapers, and radio and television advertisements. Only one of those three may consist solely of activity within 30 days of filing, and none may be more than 180 days before filing.
What is the notice posted at my workplace?
That is the Notice of Filing required by 20 CFR 656.10(d). If there is no bargaining representative, the employer must post it at the facility or location of the employment for at least 10 consecutive business days, clearly visible and unobstructed, in conspicuous places where US workers can readily read it, and must also publish it in any and all in-house media used for recruitment of similar positions. It must state that it results from the filing of an application for permanent alien labor certification, state that any person may provide documentary evidence bearing on the application to the DOL Certifying Officer, give that officer's address, state the rate of pay, and be provided between 30 and 180 days before filing.
What happens if a qualified US worker actually applies?
The employer cannot lawfully reject them in order to keep your case alive. Under 20 CFR 656.17(g), the employer prepares a signed recruitment report describing the steps taken and the results achieved, the number of hires, and the number of US workers rejected, categorised by the lawful job-related reasons for the rejections. 20 CFR 656.17(g)(2) is explicit that a US worker is able and qualified if they can acquire the necessary skills during a reasonable period of on-the-job training, and rejecting a worker for lacking skills they could acquire in that period is not a lawful job-related reason. Under 20 CFR 656.24(b)(2), the Certifying Officer decides the case on the basis of whether there is a US worker who is able, willing, qualified and available for and at the place of the job opportunity. If there is, the certification is denied. That is the design of the programme, not a failure of it.
Can I help screen the applicants, or even see the resumes?
No. 20 CFR 656.10(b)(2)(i) states that it is contrary to the best interests of US workers to have the beneficiary, or agents or attorneys for either the employer or the beneficiary, participate in interviewing or considering US workers for the job offered. Under 656.10(b)(2)(ii), the employer's representative who does that screening must be the person who normally interviews or considers applicants for comparable job opportunities that do not involve labor certifications. If you are the hiring manager for your own PERM position, that is a real conflict your employer's counsel needs to resolve before recruitment starts.
Why is there a waiting period before my case can be filed?
The mandatory recruitment steps must be completed at least 30 days before the application is filed, and the Notice of Filing must be provided between 30 and 180 days before filing. That 30-day floor is often called the quiet period, and it exists so anyone who responded to the advertising has a genuine opportunity to be considered before the employer certifies to DOL that no qualified US worker was available. On the other side, no recruitment step may be older than 180 days at filing, which is why an employer who misses the window has to run the whole campaign again.
How long does my employer have to keep all of this?
Five years. 20 CFR 656.10(f) requires the employer to retain copies of the application and all supporting documentation for 5 years from the date of filing the Application for Permanent Employment Certification. That is why the recruitment file matters long after certification is approved. If DOL audits under 20 CFR 656.20, or the case is questioned later, the file is the evidence.
This article is general information about a federal regulation, not legal advice, and no one should act on it in their own case without their own attorney. Whether a particular applicant is "qualified" under 20 CFR 656.17(g)(2), and whether any given rejection reason is lawful, are legal determinations made by the employer with counsel and reviewed by a DOL Certifying Officer — this page cannot offer a view on your situation. Anything touching a layoff, a resignation, or the job ending mid-recruitment also touches your H-1B status, the 60-day grace period, priority-date retention and AC21 portability, and belongs with your own immigration attorney. F1Jobs works with international professionals across the sponsorship arc, from the first offer through the green card queue.
