The TN visa remains one of the most flexible tools for U.S. employers to bring in Canadian and Mexican professionals under the United States–Mexico–Canada Agreement (USMCA, formerly NAFTA). But many professionals and employers find themselves asking a key question: what happens if a TN worker wants to change employers? Unlike the H-1B, the TN does not have portability provisions. This means a move to a new employer has to be handled carefully.
No Portability Like the H-1B
H-1B workers benefit from “portability,” which allows them to start working for a new employer as soon as the new petition is filed. TN professionals do not have this protection. They cannot begin working for the new employer until U.S. Citizenship and Immigration Services (USCIS) or Customs and Border Protection (CBP) authorizes the change.
Filing a Change of Employer Petition
If the professional is already in the United States and wants to remain without international travel, the new employer must file Form I-129 with USCIS. Along with the form, the TN supplement is required to specify the occupation and employment details. The employer must provide a support letter describing the role, duration of employment, and how it qualifies under the TN occupational list. The worker must also include evidence of qualifications such as degrees, licenses, or experience letters.
Premium Processing
USCIS does allow premium processing for TN petitions. By filing Form I-907 with an additional fee, employers can secure a decision within 15 calendar days. Many use this option to reduce downtime between jobs.
Reentering With an Existing TN Visa Stamp
Mexican citizens must always hold a valid TN visa in their passport to enter the United States. Unlike Canadians, who can apply directly at the port of entry, Mexican citizens cannot rely solely on an employer letter. If the visa stamp remains valid, the professional may depart and reenter the U.S. with the new employer’s letter and supporting documents. Upon admission, CBP typically issues an I-94 valid for up to three years, though the officer has discretion to shorten it based on passport validity or other factors.
Fees Involved
When filing inside the U.S., the following fees apply:
- Form I-129 filing fee: $460
- Asylum Program Fee: $600 for large employers, $300 for small employers, exempt for nonprofits
- Premium processing (optional): $2,805
There are no ACWIA or fraud prevention fees as with the H-1B.
Documentation Requirements
A successful TN change of employer filing should include:
- Form I-129 with TN classification supplement
- Employer support letter describing the job, duration, and TN occupational category
- Worker’s qualifications (degree evaluation if foreign, transcripts, licenses, or evidence of five years’ experience for management consultants)
- Copy of current I-94 and passport biographic page
- Client assignment letters if the worker will be deployed at a client site
Client-Site Assignments
Employers may assign TN professionals to client locations. However, USCIS and CBP must see a clear employer–employee relationship. The TN employer must remain the party that hires, pays, and supervises the professional. Client letters or contracts help establish the legitimacy of the arrangement.
Salary Considerations
There are no prevailing wage rules for TN professionals. Nevertheless, officers expect to see a wage consistent with professional standards in the U.S. If the salary looks too low, it may cast doubt on whether the job is truly a professional TN role. Many employers benchmark against Bureau of Labor Statistics data, O*NET, or even H-1B Level 1 prevailing wages to maintain credibility.
Qualifications for Popular TN Categories
- Systems Analyst: Requires a bachelor’s degree in computer science, IT, engineering, or a related field. Foreign degrees are acceptable if a credential evaluation shows equivalency to a U.S. bachelor’s. Unlike the H-1B, experience alone cannot substitute for a degree in this category. The position must involve analyzing and designing systems, not routine IT support.
- Management Consultant: Requires either a bachelor’s degree or five years of related professional experience. The role must remain advisory and temporary, not fill a regular management position.
Common Pitfalls to Avoid
- Assuming portability: Unlike the H-1B, TN workers cannot start with the new employer until approval is secured.
- Low salaries: Officers may doubt that a professional role is being offered if compensation falls far below U.S. norms.
- Weak client-site documentation: If the employer–employee relationship is not clearly established, the petition may be denied.
- Using H-1B-style equivalency: For Systems Analyst, experience cannot replace the required bachelor’s degree. Attempting to rely on experience-only equivalency can lead to rejection.
- Vague support letters: A generic description of duties is not enough. Officers want to see duties tied directly to the TN occupational category.
Key Takeaways
Changing employers on TN status is possible, but it is not as straightforward as the H-1B process. A worker cannot simply move jobs without either a USCIS-approved I-129 petition or CBP approval upon reentry. Employers must prepare a strong support letter, document qualifications, and be mindful of salary credibility. Premium processing can reduce delays, and existing visa stamps can sometimes be reused. With careful planning, TN professionals can transition smoothly while staying in compliance with immigration rules.
