Please contact the Office of Immigration to determine if the TN is appropriate and applicable to the case, prior to completing any offer letter to a potential scholar.

Overview of TN status

Please Note: On July 1, 2020, the United States-Mexico-Canada Agreement (USMCA) replaced the North American Free Trade Agreement (NAFTA). The criteria for TN admission under the USMCA is the same as under NAFTA.

The TN (Trade NAFTA) category was developed as part of the North American Free Trade Agreement (NAFTA), to facilitate the entry of Canadian and Mexican citizens to the United States to engage in professional business activities on a temporary basis.

Only occupations specified in of the NAFTA treaty can serve as the basis for TN employment. also stipulates the minimum qualifications for entry into the U.S.in each occupation. 

Both Canadian and Mexican citizens can be admitted to the United States in TN status in increments of up to three years.  Extensions of stay are also granted in up to three-year increments. There is no cumulative total limit on the time a Canadian or Mexican citizen can be in TN status. Status can be renewed indefinitely, provided that the stay remains temporary in nature (e.g. cannot be in a tenure-track or permanent employment position).

TN Eligibility Requirements

  1. Applicant must be a citizen of Canada or Mexico
  2. Applicant must possess the minimum qualifications of a member of one of the professions listed in
  3. Entry must be temporary in nature (no tenure-track position)
  4. Job must constitute pre-arranged professional activity for a U.S. entity, within one of the professions listed in

How do I apply for TN status?

  • Apply for the TN visa in their home country (Canadian citizens do not require a visa and may obtain TN status at a U.S. Port of Entry) or
  • Have the 麻豆相关报道 Office of Immigration file an I-129 petition sponsoring either a change of status to TN or extension of status of TN within the United States.

Timeline and Preparing for TN Status

  1. Apply for a TN visa or status abroad (either for a TN visa at a U.S. Consulate for citizens of Mexico or for TN status at a U.S. Port of Entry for citizens of Canada) is often the quickest way to obtain TN status since no petition must be filed with U.S. Citizenship and Immigration Services (USCIS) in advance. Mexican citizens who will apply for a visa at a U.S. Consulate must plan at least 2 months in advance to allow enough time for obtaining an appointment for the visa interview and for visa processing. Canadian citizens who will apply for TN status at the port of entry should make sure to obtain all supporting documents needed for TN status at least 2 weeks prior to their intended entry to the U.S.
  2. The 麻豆相关报道Office of Immigration will process an I-129 petition for change of status to TN or an extension of stay if scholar is within the United States. The Office of Immigration must submit the I-129 petition to U.S. Citizenship and Immigration Services (USCIS) as early as 6 months before the intended start date of the TN. The TN application process is very long and requires much documentation from both the department and applicant.  It is important that the department and scholar prepare for this process well in advance of the start date of employment. The fee for the I-129 is $460.

TN Application & Extension

Change of Status Inside the U.S. (an uncommon process)

If the Canadian or Mexican citizen is present in the United States in another nonimmigrant classification (i.e. F-1, H-1B, etc.), it is possible to file a change of status petition with the U.S. Citizenship and Immigration Services (USCIS) without exiting the United States. An individual must have a valid nonimmigrant status in order to be eligible for a change of status and must wait until the change of status is approved before he or she begins employment in TN status.

If a Mexican citizen changes to TN within the U.S., the next time they exit the United States for travel, they must get a TN visa prior to returning to the U.S. to resume work in TN status.

麻豆相关报道 departments who wish to process a TN petition on behalf of an employee must contact the Office of Immigration to initiate processing.  Please be aware that a change-of-status to TN is rare since obtaining TN status at the border or abroad is often significantly faster.

  1. File Form I-129 and Nonimmigrant Classification Based on Free Trade Agreement Supplement

  5. Provide evidence that the job is in one of the occupations listed in Appendix 1603.D.1

*Note: No travel outside the U.S. while a change of status petition is pending. Once the I-539 petition is submitted to USCIS, the TD applicant cannot leave the United States for any reason.  If the TD leaves the U.S., even for a Caribbean cruise, the I-539 petition will be considered 鈥渁bandoned鈥� and the case will be cancelled by USCIS.  Only once the I-539 petition has been approved will the TD be able to travel internationally.  Also, please be aware that the I-539 petition approval is not a visa. The TD dependent will need to apply for a new visa at a U.S. Embassy or Consulate the next time they travel beyond North America.

Dependents Currently on B-1/B-2 Visitor Visa

  1. If a dependent is currently on a B-1/B-2 visitor visa and they want to apply to change status to an TD dependent visa status, applying for a change of status within the first 90 days of entry to the U.S. in B-1/B-2 status will likely result in a denial and will be considered fraudulent entry based on a misrepresentation of status based on 鈥� Inconsistent Conduct Within 90 Days of Entry. This change to the Foreign Affairs Manual was published on September 20, 2017. 
  2. USCIS now requires someone in another visa status to maintain their status continuously while awaiting a change of status approval. This means that in addition to filing an I-539 petition to change status to TD dependent status, you must either maintain your current visa status until a decision is made or file I-539 petitions to change to or extend B-1/B-2 status while the change of status to TD is pending. The Office of Immigration advises that an immigration attorney be retained if the TD applicant is in this scenario.

A TD dependent spouse or child cannot work while in TD status.  If a TD dependent wishes to work, they must apply for a change of status to a visa type that allows employment.
