TN Visa Frequently Asked Questions

What is the purpose of the TN visa?

The TN visa is designed to facilitate the temporary entry of Canadian and Mexican citizens into the United States to work in specific professional occupations listed under NAFTA.

Who is eligible for a TN visa?

To be eligible for a TN visa, you must meet the following criteria:

Be a citizen of Canada or Mexico.

Have a job offer from a U.S. employer in a NAFTA-listed professional occupation.

Possess the necessary qualifications and credentials for that profession.

What are the eligible professions under the TN visa?

NAFTA specifies a list of eligible professions, including but not limited to engineers, scientists, computer systems analysts, lawyers, pharmacists, and management consultants. Each profession has specific requirements.

How long can I stay in the U.S. on a TN visa?

TN visa holders are typically granted an initial period of stay of up to three years, with the possibility of extensions in three-year increments. The visa is renewable indefinitely as long as you continue to meet the requirements.

Can my family accompany me on a TN visa?

Yes, your spouse and unmarried children under 21 may accompany you to the U.S. on TD visas, which are dependent visas. However, TD visa holders are not authorized to work in the U.S.

Can I change employers while on a TN visa?

Yes, you can change employers while on a TN visa, but you must have a new job offer in a NAFTA-listed profession, and your new employer must file a new TN petition on your behalf.

How do I apply for a TN visa?

The process generally involves:

Obtaining a job offer from a U.S. employer in a NAFTA-listed profession.

Providing the required documentation and credentials.

Applying for a TN visa at a U.S. embassy or consulate in Canada or Mexico or at a U.S. port of entry (for Canadian citizens only). You can also submit the petition to USCIS and send it to the border or consulate with an approval notice.

Is there an annual cap on the number of TN visas issued?

There is no annual numerical cap on the number of TN visas issued to Canadian or Mexican citizens.

Can I apply for permanent residency (a green card) while on a TN visa?

Yes, it is possible to apply for permanent residency while on a TN visa, but you must meet the eligibility criteria for an employment-based green card category.

Can I travel outside the U.S. while on a TN visa?

Yes, you can travel outside the U.S. and re-enter while on a TN visa, provided you have a valid TN visa stamp in your passport and a valid TN approval notice. However, it’s essential to ensure that your travel plans align with your TN status and employment.

To the entire Davidson Law Group team, thank you so much for all the support during the past three years of my immigration journey in the US. They were especially supportive and responsive to all my queries about the different visas and were always prompt and kind. I especially appreciated it when Leyla got back to me beyond working hours on a Friday with, "Congratulations, your H1B has been picked." It definitely made my and my close ones' weekend a tad better. I would recommend them for sure just because I appreciated their humane approach to all of their cases. Kudos to all of you.
