Who Qualifies for TN Status?

TN status is a temporary nonimmigrant classification for qualifying citizens of Mexico and Canada who will perform professional-level services in the United States. The applicant must have a profession listed under the USMCA professional categories, a prearranged job with a U.S. employer or qualifying professional arrangement, and the education, license, certificate, or experience required for the specific profession.

• The applicant must be a citizen of Mexico or Canada.
• The U.S. position must correspond to a qualifying USMCA profession.
• The employment must be prearranged and professional in nature.
• The applicant must possess the profession-specific qualifications.
• Self-employment is not permitted under TN classification.

Mexican TN Visa Application Process

1. Identify the correct USMCA profession and confirm that the offered position matches that profession.
2. Obtain a detailed employment/support letter describing the professional role, duties, compensation, location, and expected period of employment.
3. Collect evidence of the profession-specific education, license, certificate, or qualifying experience.
4. Complete Form DS-160 accurately.
5. Pay the current TN/TD nonimmigrant visa application fee of $185.
6. Follow the appointment and document instructions of the U.S. embassy or consulate handling the application.
7. Attend the visa interview and provide the requested supporting evidence.
8. If approved, use the TN visa to seek admission to the United States. The visa validity period and the period of authorized TN stay are separate concepts.

The Department of State can request additional documents to establish that the applicant qualifies for the TN category.

TN Admission Can Be Up to Three Years

A qualifying TN nonimmigrant may generally be admitted for a period not exceeding three years. The visa expiration date in a Mexican passport should not be confused with the authorized period of stay granted at admission. The admission record controls the authorized stay in the United States.

Changing or Adding a TN Employer

TN authorization is tied to the qualifying professional employment described in the TN application. A TN worker who wants to change employers or add employment must obtain the required authorization before beginning the new or additional employment.

USCIS identifies Form I-129 as one route for obtaining authorization for a new or additional TN employer. A TN professional may also seek admission based on a new qualifying employer's documentation at an appropriate port of entry or preclearance location, where permitted.

TD Dependents

The spouse and unmarried children under 21 of a TN nonimmigrant may qualify for TD dependent classification. TD dependents do not have employment authorization merely from TD status, although they may attend school.

TD visa requirements depend on the dependent's nationality. A dependent who is not otherwise visa-exempt may need a TD visa before seeking admission, while eligible Canadian citizens generally do not need a TD visa.

Profession-Specific Qualification Rules

TN qualification cannot be determined from a job title alone. The offered duties must fit a listed USMCA profession and the applicant must satisfy that profession's specific credential standard. For example, Engineer generally requires a Baccalaureate or Licenciatura degree or a state/provincial license; Computer Systems Analyst may qualify through a degree or specified post-secondary credential plus three years of experience; and Management Consultant has an express five-year experience alternative.

Scientific Technician/Technologist is different: the applicant must demonstrate the required theoretical scientific knowledge and the ability to solve practical problems or apply the relevant principles to research while directly supporting qualifying professionals. Therefore, one generic credential rule cannot safely be applied to every TN occupation.

TN and Permanent Residence

TN is a temporary nonimmigrant classification and is not itself an immigrant status. A TN professional may later pursue permanent residence through an independently available immigrant pathway, but the person must carefully consider immigrant-intent and admission issues because TN does not provide the same statutory dual-intent treatment as H-1B and L-1 classifications.

There is no universal “90-day rule” that makes a TN-to-Green-Card strategy safe after a particular number of days. The appropriate strategy depends on the person's circumstances and should be evaluated before filing an immigrant petition, adjustment application, or new nonimmigrant visa application.

Common TN Problems

• The offered job does not actually fit the selected USMCA profession.
• The applicant relies on work experience where the profession requires a degree and does not provide an experience alternative.
• The degree, diploma, certificate, or license does not satisfy the profession-specific requirement.
• The support letter does not clearly explain the professional duties or remuneration.
• The applicant's documents do not adequately establish prior experience when experience is required.
• The employment arrangement is inconsistent with TN requirements or amounts to prohibited self-employment.
• The applicant begins work for a new or additional employer before obtaining the required authorization.
• The applicant confuses visa validity with the authorized period of TN admission.
