What Is an LCA for an H-1B Visa? A Plain-English Guide

The Labor Condition Application is the DOL filing that locks in your H-1B wage level, worksite, and now your lottery odds.

Somewhere between your offer letter and your H-1B petition, someone on the HR or immigration team mentions "the LCA." Nobody explains what it is, and the acronym sounds like paperwork you don't need to understand. You do — because the LCA is where your wage level gets locked in, and as of 2026, that wage level now also shapes your odds in the H-1B lottery.

What an LCA actually is

The Labor Condition Application (Form ETA-9035) is a filing your employer submits to the US Department of Labor before it can file your H-1B petition with USCIS. It is not a job offer, and it is not filed with USCIS at all — it's a DOL attestation. In it, your employer promises three things: it will pay you at least the prevailing wage or the actual wage paid to similarly employed workers, whichever is higher, for your specific occupation and worksite; your employment won't adversely affect the working conditions of similarly employed US workers; and there is no strike or lockout in the relevant occupation at that worksite. USCIS requires a certified LCA attached to your H-1B petition — without it, the petition doesn't get filed.

The LCA is where the DOL wage level for your role gets set, and it's worth understanding because that single classification decision now has downstream effects far beyond your paycheck.

The four DOL wage levels

Every LCA assigns your role one of four wage levels, derived from Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) data for your occupation code and geographic area. The employer — not you — selects the level, based on how the job description matches criteria like independent judgment, supervisory responsibility, and years of relevant experience typically required.

Level isn't about your personal seniority or degree alone — it's about how the specific job is described and classified against OEWS survey data for that occupation and metro area. Two people with identical backgrounds can end up at different levels if their job descriptions differ. For the full mechanics of how DOL calculates each level, see our breakdown of DOL prevailing wage levels for H-1B.

How your LCA wage level now feeds the H-1B lottery

This is the part most candidates don't know yet, and it's the reason the LCA deserves more attention than it used to get. Under the wage-weighted selection rule that took effect 2026-02-27, USCIS no longer runs a flat random draw for cap-subject H-1B registrations. Instead, each registration is entered into the selection pool a number of times based on the wage level tied to the offered role: Level IV gets four entries, Level III gets three, Level II gets two, and Level I gets one.

That means the wage level your employer selects on your LCA — set months before the lottery even opens — has a direct, mechanical effect on your selection odds. A Level I offer isn't disqualifying, but it enters the pool with a fraction of the weight of a Level III or IV offer for the same role. Because the wage level is determined by how the job is described and where it's located, it's worth raising with your employer or immigration counsel before the LCA is filed, not after you've already been through a lottery cycle. For the full mechanism, including how DOL and USCIS reconcile the wage data with the lottery pool, see our explainer on the wage-weighted H-1B lottery mechanism.

How an LCA actually gets filed

The LCA is a DOL process that happens entirely before USCIS ever sees your petition. In sequence:

1. Employer defines the role. Job duties, minimum requirements, and worksite location are documented — this is what ultimately drives the wage level.
2. Wage level and prevailing wage are determined. The employer maps the role's SOC occupation code and location to OEWS wage data to land on a wage level and dollar figure.
3. Employer files the LCA electronically with DOL through the FLAG system (Form ETA-9035).
4. DOL reviews the filing for completeness and certifies it, or flags it for further review if something is incomplete or inconsistent.
5. Employer posts required notice of the filing at the intended worksite(s), satisfying the LCA's public-notice attestation.
6. Certified LCA is attached to Form I-129, the H-1B petition filed with USCIS.
7. USCIS reviews the petition, including whether the wage and worksite attestations line up with the specialty-occupation claim and the offered role.

Because LCA and prevailing-wage rules can shift, don't treat an older LCA filing — yours from a prior job, or one you found in a public database — as a template for what your current employer's filing should look like. Confirm the current requirements with your employer's immigration counsel or DOL's own guidance before relying on it.

Where to check LCA filings for a specific employer

LCA filings are public. The Department of Labor publishes LCA disclosure data, and USCIS separately maintains the H-1B Employer Data Hub, both searchable by employer name. These let you see what wage level and location a company has historically certified for roles similar to the one you're considering — useful research when you're evaluating an offer or building a list of employers to target. Our guide to using the USCIS H-1B Employer Data Hub to build a target company list walks through how to pull and read that data, and our companion piece on how to search LCA filings for an H-1B visa covers the search mechanics directly. Keep in mind these records tell you what a company has done in the past, not what wage level your own specific offer will land on — that depends on your job description and worksite.

When your LCA needs to change

An LCA is tied to a specific role, wage level, and worksite — not to you as a person indefinitely. Certain changes during your employment can require a new or amended LCA, and sometimes an amended H-1B petition to go with it:

• Moving to a worksite outside the geographic area covered by your certified LCA
• A material change in job duties that no longer matches the original LCA's description
• A wage level or salary change that falls below what the LCA attests to

A title change with no real change in duties or pay does not automatically require a new LCA, but the two situations get confused constantly — and getting it wrong can put your status at risk. We cover this distinction in detail in our guide on when a promotion or title change requires an LCA or H-1B amendment. If you're facing a role change, relocation, or promotion, confirm with your employer's immigration counsel before the change takes effect, not after.

Common mistakes

• Assuming the LCA is the H-1B petition. It isn't. It's a DOL prerequisite filed before USCIS is ever involved, and the two agencies review different things.
• Not asking about your wage level before the lottery. Once the LCA is filed and the registration submitted, the lottery-entry weight tied to that level is locked in for that cycle.
• Treating an old LCA as a current template. DOL wage data, prevailing wage figures, and filing requirements update on their own schedule — an LCA from last year or a different employer isn't a safe stand-in.
• Confusing a title change with a material duty change. One may require nothing; the other may require an amendment. Guessing wrong here is a status risk, not a paperwork inconvenience.
• Relying on public LCA data as a guarantee. A company's past filings show history, not a commitment about how your specific role will be classified.

Frequently asked questions

What does LCA stand for and what does it actually do? LCA stands for Labor Condition Application, the document a prospective H-1B employer files with the Department of Labor before filing the H-1B petition itself. It is an attestation, not a job offer confirmation — the employer promises to pay the prevailing or actual wage, whichever is higher, for the specific occupation and worksite, and to provide working conditions that will not adversely affect similarly employed US workers. USCIS will not accept an H-1B petition without a certified LCA attached.

What are the four DOL wage levels on an LCA? The four wage levels, based on Bureau of Labor Statistics Occupational Employment and Wage Statistics data, run from Level I (entry) through Level IV (fully competent). The employer selects the level that matches the actual duties, education requirement, and supervisory scope of the role, and the LCA attests to paying at least that wage. The level is set at the job-description stage, before the H-1B petition is ever filed.

Does the wage level on my LCA affect my H-1B lottery odds? Yes, under the wage-weighted selection rule that took effect 2026-02-27. Each registration now gets lottery entries based on the offered wage level, Level IV gets four entries, Level III gets three, Level II gets two, and Level I gets one. A Level I offer is not disqualifying, but it competes with meaningfully worse odds than a higher-level offer in the same pool.

Where can I look up a company's past LCA filings? The Department of Labor publishes LCA disclosure data, and USCIS separately publishes the H-1B Employer Data Hub, both searchable by employer name. These records show the certified wage level, worksite, and occupation code for past filings, which is useful for researching how an employer has historically classified similar roles. They will not tell you what level your own offer will use, since that depends on your specific job description and location.

What happens to my LCA if my job title, duties, or worksite change? A meaningful change can require a new or amended LCA and, depending on the change, an amended H-1B petition. Moving outside the geographic area covered by the certified LCA, or a material change in job duties or wage level, generally triggers this requirement. A title change alone with no real change in duties does not automatically require action, but the two are often confused, so confirm any worksite or role change with your employer's immigration counsel before it happens.

The LCA looks like background paperwork until you realize it quietly sets your wage level, your worksite, and now a real piece of your lottery odds — well before you ever see the H-1B petition itself.
