The nonimmigrant USMCA Professional (TN) visa permits citizens of Canada and Mexico to work temporarily in the United States in certain occupations. At Yale, the most typical use of the TN visa is for salaried employees doing teaching or research. For academic appointments (postdoctoral researcher, instructor, etc…) the basic steps are as follows:

  • The host department at Yale contacts the OISS adviser for that department
  • Once OISS confirms TN eligibility the department sets up an OISS Connect record
  • The department sends the OISS adviser a draft TN support letter (see details below)
  • The final letter is sent to the scholar with instructions
  • The Canadian scholar presents evidence of citizenship, degree (in a field listed on the TN list), the letter, pays $50.00 (Canadians) end enters the U.S.
  • The Mexican scholar must apply for a TN visa at a U.S. embassy, and then enter the U.S.
  • The scholar registers with OISS upon arrival in New Haven

Canadians driving in to the U.S. must use a pre-clearance post of entry.

Complete information about the TN requirements for both citizens of Mexico and Canada.

TN status is granted when the scholar enters the U.S. for up to a three year period based on the actual dates of employment. TN status is valid for the time the scholar is employed, up to the expiration of the I-94 record. When the employment is concluded, there is no grace period of additional time to remain in the U.S.

Spouses and dependent children of persons in TN status hold TD status.


TN Letter

The letter should contain the following information:

  • State that it is an offer of employment and name the scholar
  • Be addressed to “U.S. Customs and Border Protection”
  • Contain a thorough description of the job duties and dates of employment; from-to not exceed three years and list the salary
  • Ask OISS what the correct USMCA occupation category is, and include this in the letter
  • Conclude with contact information, work site location address and phone number

TN Extensions

Once the host department has updated OISS Connect and issued a new TN letter to the scholar the scholar can re-enter the U.S. (from Canada) by traveling and repeating steps 4 and 5 above. It is rarely worth the expense of paying for a TN extension within the U.S., but it is possible following the steps below at least 6 months prior to the expiration of the current TN.
