Changing Employers on a TN: New Petition, Border Application or Concurrent TN, and When You Can Start

There is no TN transfer. Your new employer needs its own TN approval first, and the route depends on your passport. Here is how each one works and when you can start.

Part of our guide to the TN visa.

As of November 1, 2026, there is no "TN visa transfer" in the H-1B sense. A TN approval covers one employer, so changing jobs means getting a new TN approval for the new employer, and you cannot start that job until you have it. There are three ways to get one: the new employer files Form I-129 with USCIS while you stay in the US (Canadians and Mexicans), you apply at a US port of entry or pre-flight station with the new employer's letter (Canadians), or you get a new TN visa at a US consulate and re-enter (Mexicans). Adding a second TN employer works the same way.

Status line (2026-11-01). TN rules are in effect and unchanged; the USMCA was "not renewed" on 2026-07-01 but "remains in force" (USTR). The 60-day worker grace period, which covers TN, still applies; DHS's proposal to end it (RIN 1615-AD22) takes comments until 2026-11-10 and stays a proposal unless a final rule is published. From 2026-11-09, USCIS accepts only the 09/09/26 edition of Form I-129.

TN visa transfer: can you move your TN to a new employer?

Not the way H-1B workers do. A TN covers one employer, so a job change needs a new TN approval for the new employer: a USCIS Form I-129 petition, a Canadian border application, or a new Mexican TN visa from a consulate. Under 8 CFR 214.6(i), you cannot work for the new employer before that approval.

"Employment with a different or with an additional employer is not authorized prior to Department approval of the request." (8 CFR 214.6(i)(1))

The USCIS Policy Manual, Volume 2, Part P, Chapter 5 (current as of 2026-10-27) says the same and describes the readmission and new-visa alternatives. If you are still checking whether you qualify for TN at all, start with our complete TN guide for Canadians and Mexicans.

Common misconception: "A TN transfer works like H-1B portability, so I can start once the petition is filed."

Correction: Portability is an H-1B rule. Under 8 CFR 214.2(h)(2)(i)(H), an eligible H-1B worker may start new or concurrent employment once a nonfrivolous H-1B petition is filed, or on the requested start date if later. TN has no equivalent; a receipt notice does not let you start.

Three routes to a new TN employer, by nationality

Each route ends with a TN approval or admission for the new employer.

TN change-of-employer routes, as of 2026-11-01

Route	Canadian citizens	Mexican citizens	When you can start	Main trade-off
New employer files Form I-129 with USCIS	Yes, while in the US	Yes, while in the US	After USCIS approves the petition	You stay in the US but wait: 4.5 months for 80% of TN cases, or 15 business days with premium processing
Port of entry or pre-flight station	Yes, no visa needed	Only with a new TN visa (next row)	When CBP admits you for the new employer	Fast, but you leave, and the officer decides on the spot
New TN visa at a US embassy or consulate	Not needed	Yes	When CBP admits you on the new visa	Interview, online-presence review, appointment waits
Add a second, concurrent employer	Any route above	Any route above	After that employer's own approval	The first job continues

Processing figures come from the USCIS processing-times tool, read on 2026-11-01. Check the live tool; the numbers move.

Route 1: your new employer files Form I-129

The new employer is the petitioner. Under 8 CFR 214.6(i)(1), the petition needs "a letter from the new employer describing the services to be performed, the time needed to render such services, and the terms of remuneration for services." Our guide to what a TN employer support letter must cover walks through each element. The mechanics in November 2026:

Paper filing. TN is not on USCIS's list of I-129 categories that can be filed by PDF upload (updated 2026-10-07), so the petition goes by mail.
Edition and address. The USCIS Form I-129 page says: "Starting Nov. 9, 2026, we will accept only the 09/09/26 edition of Form I-129." Filing locations changed on 2026-10-07; a package sent to an old address is accepted only if postmarked on or before 2026-11-09.
Fees. The G-1055 fee schedule (edition 10/26/26) lists $1,015 for a paper TN petition, or $510 for a small employer or nonprofit, plus an Asylum Program Fee of $600 ($300 for a small employer, $0 for a nonprofit).
Premium processing. With Form I-907 and $2,965, USCIS commits to "adjudicative action to be taken within 15 business days," per its premium processing page, which lists TN for Canada and Mexico. Action can be an approval, a denial, a request for evidence (RFE) or a notice of intent to deny. An RFE stops the clock; a new 15-business-day period starts when USCIS receives the response.

In USCIS's FY2026 Q1-Q3 I-129 data, 94.9% of USCIS-filed TN petitions (initial and extensions) were approved, as approvals over approvals plus denials, with a 13.0% RFE rate. Those decisions predate PA-2026-05 (in effect since 2026-08-05, challenged in AAUP v. Mullin), which lets USCIS deny without first sending an RFE, so a complete first filing matters more (our reading).

Route 2: Canadians apply at the border

Canadians need no TN visa. The USCIS TN page says you can establish eligibility at certain CBP-designated ports of entry or a pre-clearance/pre-flight station, with proof of Canadian citizenship, the employer's letter and, if applicable, a credentials evaluation. For job changes, 8 CFR 214.6(i)(2) allows readmission "for the purpose of presenting documentation from a different or additional" employer.

If CBP admits you in TN status for the new employer, you can start; a refusal leaves you outside the US without the new TN. The TN online-presence review (in effect since 2026-10-01) is a visa-stage step; MIT's International Students Office notes it "does not apply to Canadian citizens who do not apply for U.S. entry visa stamps."

Route 3: Mexicans get a new TN visa

The Policy Manual: "A Mexican citizen seeking to change or add a U.S. employer may depart the United States and seek a new visa from a U.S. embassy or consulate before readmission." In late 2026 that means:

Online-presence review for TN and TD visa applicants, in effect since 2026-10-01.
An in-person interview. Under State's September 2025 interview-waiver update, nonimmigrant applicants generally interview in person; waivers remain only for B-1/B-2 (and Border Crossing Card) and H-2A renewals within 12 months, plus diplomatic classes.
Appointment waits. Check the live Global Visa Wait Times page.
Administrative processing. A 221(g) hold "can delay issuance for weeks or months," according to a 2026-10-30 Mintz outlook.

A Mexican citizen who takes Route 1 and travels later runs into 8 CFR 214.6(h)(2): "Citizens of Mexico must present a valid passport and a valid, unexpired TN nonimmigrant visa when applying for readmission." Ask the attorney whether your current visa supports re-entry for the new job. Our guide to the TN visa for Mexican citizens covers the consular steps.

When can you start working for the new TN employer?

Only once the new TN exists: when USCIS approves the I-129, or when CBP admits you in TN status for that employer. Until then, your current TN job is the only one you are authorized to do.

Worked timeline: an offer accepted on 2026-11-02

A hypothetical Canadian software engineer in TN status, with an I-94 valid into 2028, accepts an offer on Monday, November 2, 2026, for a Monday, December 7 start.

Two paths to a December 7 start (dates by our arithmetic, as of 2026-11-01)

Date	Premium I-129 path	Border path (Canadians only)
Mon 2026-11-02	Accept the offer and keep the current job; the employer's attorney prepares the letter and a 09/09/26-edition I-129	Same letter; gather passport, degree and any credential evaluation
Fri 2026-11-06	I-129 and I-907 reach the USCIS filing address	Keep working
Tue 2026-12-01	15th business day after receipt, skipping Veterans Day (11-11) and Thanksgiving (11-26): USCIS action due	Keep working
Early December	If approved, start 12-07; an RFE stops the clock and pushes this back	After the last day at the current job (time it with the attorney, since the admission is for the new employer), apply at a pre-flight station or land port; if admitted, start 12-07
About 2027-03-21	Without premium: 4.5 months after 11-06, using the 80% figure read on 2026-11-01	Not applicable

The gap case: resigning before the approval

Suppose the same engineer resigns effective Friday, November 13, before any new TN exists. Counting November 14 as day 1, day 60 of the grace period is Tuesday, January 12, 2027, or the end of the authorized stay if sooner (our arithmetic). Whether you may remain while a petition is still pending after day 60 is a question for the new employer's immigration attorney; our guide for anyone laid off on a TN, L-1, O-1 or E-3 covers the clock.

Can you have two TN employers at the same time?

Yes. 8 CFR 214.6(i)(1) covers a TN worker who "seeks to change or add a United States employer," and the USCIS TN page describes a "prearranged full-time or part-time job." Each approval rests on one employer's letter describing the services, the time needed and the pay, so a second job is outside it until that employer's own approval exists. Concurrent H-1B employment, by contrast, can start on filing.

Side clients. USCIS describes TN work as a job "for a U.S. employer or entity." On our reading, a short consulting engagement for another US client is another employer, so ask an attorney before you take one.
Adding is not replacing. A border admission produces a new I-94, so ask an attorney before you travel how to present an add-an-employer request.

Do you need to leave the US to change TN employers?

No. Route 1 keeps you in the US from filing to approval. Leaving is an option for Canadians who want the border route and for Mexicans who want a new visa, not a requirement. If a petition is pending and you are thinking about travel, ask the attorney first how a trip would affect the pending request.

Does moving to a sister company count as a new employer?

Sometimes. The Policy Manual says a worker "transferred to another location (for example, another branch or office) by the same U.S. employer to perform the same services" needs no new petition or readmission. A move to "a separately incorporated subsidiary or affiliate" is different: "the TN nonimmigrant (and any dependents) must file a new Form I-129."

What happens to your TN status if you quit?

When the approved job ends, 8 CFR 214.1(l)(2) gives a grace period of "up to 60 consecutive days or until the end of the authorized validity period, whichever is shorter," once per authorized validity period, with no work allowed, and "DHS may eliminate or shorten this 60-day period as a matter of discretion." The Federal Register proposal to remove it (docket USCIS-2026-0364) names TN, takes comments on or before November 10, 2026, and had about 27,000 comments as of 2026-11-01. Nothing changes unless DHS publishes a final rule.

Your family's TD status lasts no longer than your authorized period, per the USCIS TN page; dependents can extend alongside you, and Mexican TD dependents who travel after an extension need a new TD visa to return. See our explainer on TD status for spouses and children.

TN vs H-1B when you switch employers

This is where the two categories split; our guide to how an H-1B transfer works covers the H-1B side.

Changing employers, TN vs H-1B (as of 2026-11-01)

Question	H-1B	TN
Start work with the new employer	On filing a nonfrivolous petition, or the requested start date if later (8 CFR 214.2(h)(2)(i)(H))	Only after approval or admission (8 CFR 214.6(i))
Second, concurrent employer	Can start on filing	Needs its own approval first
Border option	No; the new employer always files with USCIS	Canadians at a port or pre-flight station; Mexicans with a new visa
Proclamation 11069 ($100,000 entry restriction)	Covers H-1B; in effect on paper, fee blocked by courts	Never names TN
9-11 fee for covered employers	Applies to H-1B and L-1 petitions	Does not apply
60-day worker grace period	In effect; elimination proposed	In effect; elimination proposed

DHS's separate proposal to stop deferring to prior approvals (RIN 1615-AD26, comments close 2026-11-13) targets I-129 extensions; a new employer's petition is a fresh case either way (our reading; see our deference explainer).

How to change TN employers without a gap

Check the job against the USMCA profession list and your degree or license, using our complete TN guide.
Ask the new employer's immigration attorney for a support letter covering services, time needed and pay, the three items in 8 CFR 214.6(i)(1).
Decide with the attorney between Form I-129 with USCIS, a CBP port of entry or pre-flight station (Canadians), or a US consulate (Mexicans).
Confirm the petition uses the 09/09/26 edition of Form I-129 and the current USCIS filing address, and whether Form I-907 premium processing is in the plan.
Track the receipt number in USCIS Case Status Online, and make sure any RFE is answered completely.
Keep working only for your current employer until you hold the I-797 approval or a CBP admission for the new one.
Download your new I-94 from CBP's I-94 website after any admission and check the class, date and name.
Plan TD paperwork with the attorney: Form I-539 extensions in the US, or new TD visas for Mexican dependents who travel.

Petition and status questions go to a licensed immigration attorney, usually the new employer's; if you are moving from F-1 OPT into your first TN, your DSO handles the SEVIS side.

Common mistakes

Starting early. Paid onboarding and training are still work for the new employer; they wait for the approval or the admission.
Resigning first and counting on 60 days. The grace period is discretionary, once per validity period, capped by your authorized stay and proposed for elimination.
Calling an affiliate the same employer. A separately incorporated subsidiary or affiliate needs a new I-129.
Mailing the 02/27/26 I-129 edition on or after 2026-11-09. From that date USCIS accepts only the 09/09/26 edition.
Crossing the border unprepared. The officer decides at the counter; bring the letter, proof of citizenship and credentials.
Assuming an old Mexican TN visa covers re-entry for the new job. Confirm with the attorney before any trip.

Frequently asked questions

Can I transfer my TN to a new employer?

Not in the H-1B sense. A TN covers one employer, so a new employer needs its own TN approval, through a Form I-129 approved by USCIS, a Canadian admission at a port of entry or pre-flight station, or a new TN visa for Mexican citizens. As of November 1, 2026, these 8 CFR 214.6 rules are unchanged.

Can I start working for my new employer before the new TN is approved?

No. Under 8 CFR 214.6(i)(1), employment with a different or additional employer is not authorized before approval. Unlike H-1B portability, a filed petition or a receipt notice is not enough. You start after USCIS approves the I-129 or after CBP admits you in TN status for that employer.

Can I have two TN employers at the same time?

Yes. The regulation covers a TN worker who seeks to change or add an employer, and USCIS allows part-time TN jobs. Each employer needs its own TN approval, because each approval rests on that employer's letter, and the second job cannot begin until its approval exists.

Do I need to leave the US to change TN employers?

No. Your new employer can file Form I-129 with USCIS while you stay in the US, and you can start once it is approved. Leaving is an alternative, not a requirement, for Canadians who apply at the border or Mexicans who get a new TN visa at a consulate.

What happens to my TN status if I quit?

Your TN employment ends. As of November 1, 2026 you may have a discretionary grace period of up to 60 days, or until your authorized stay ends if sooner, to have a new employer file, change status or leave, with no work allowed. DHS has proposed ending it, with comments due November 10, 2026, but no final rule exists.
