Step-by-Step Guide to Applying for a TN Visa
Understanding the TN Visa
The TN Visa is a non-immigrant visa that allows citizens of Canada and Mexico to work in the United States under the United States-Mexico-Canada Agreement (USMCA). This visa is specifically designed for professionals in certain fields, allowing them to enter the U.S. for work purposes. Understanding the application process is crucial for ensuring a smooth transition to employment in the U.S.

Eligibility Requirements
Before applying for a TN Visa, it’s important to confirm your eligibility. Candidates must be citizens of Canada or Mexico and should have a job offer in one of the approved professions listed under USMCA. Additionally, applicants must possess the necessary qualifications for their profession, such as degrees or certifications.
Canadian applicants benefit from a more straightforward process since they generally don’t need to apply for a visa at a U.S. consulate. Instead, they can apply at a U.S. port of entry. Mexican applicants, however, must obtain a TN Visa at a U.S. consulate before entering the United States.
Preparing Your Application
Preparation is key when applying for a TN Visa. Start by gathering all necessary documentation, which includes:
- A valid passport
- A letter from your prospective employer detailing the job role, responsibilities, and duration of employment
- Proof of professional qualifications, such as degrees or licenses
Make sure your employer's letter clearly outlines how your role fits under the USMCA-approved professions.

Applying at the Border
Canadian citizens can apply for a TN Visa directly at designated U.S. ports of entry or pre-clearance stations. When applying, present all your documentation to the U.S. Customs and Border Protection (CBP) officer. After reviewing your application, the officer will decide whether to grant you entry under TN status.
If successful, you’ll receive Form I-94, which serves as proof of your legal status in the U.S. It’s essential to keep this form safe during your stay.
Steps for Mexican Citizens
Mexican citizens must follow a slightly different procedure. Begin by scheduling an appointment at a U.S. consulate or embassy in Mexico. During your appointment, you’ll need to present your documentation and attend an interview.

If your application is approved, you’ll receive a TN Visa stamp in your passport, allowing you to travel to the U.S. and apply for admission as a TN non-immigrant at a port of entry.
Maintaining Your TN Status
Once in the United States under TN status, it’s important to comply with all regulations to maintain your visa status. This includes working only in the role specified in your application and adhering to any conditions set by your employer or the U.S. government.
The TN Visa is valid for up to three years, and extensions are possible if you continue to meet eligibility criteria and have ongoing employment.
Seeking Extensions or Changes
If you wish to extend your stay beyond the initial period or change employers, you must file Form I-129 with the U.S. Citizenship and Immigration Services (USCIS). This application should include supporting documentation similar to what was provided initially.

Planning extensions ahead of time will help avoid any disruptions in your work authorization and stay in the U.S.
Final Thoughts
Navigating the TN Visa application process can seem daunting, but with careful preparation and attention to detail, it can be managed successfully. Always ensure you have up-to-date information regarding visa requirements and seek professional advice if needed to ensure compliance with U.S. immigration laws.
