How the TN visa works
TN is for citizens of Canada and Mexico working in one of the professions on the USMCA list. There is no cap, no lottery, and no petition for most applicants. With a job offer and an employer support letter, Canadian citizens are visa-exempt and present their documents at a U.S. port of entry, receiving status the same day; Mexican citizens apply for a TN visa at a U.S. consulate first. The exception is someone already in the U.S. who changes to or extends TN status, where the employer files Form I-129 with USCIS. What matters is that your degree or credentials match a listed profession and that the offer is for a role on that list. TN does not allow dual intent, so you cannot use it to pursue a green card. TN is granted for up to three years and renews indefinitely.

Which companies sponsor the most TN visas for Scientists?
Quest Diagnostics has the most, with 221 live TN jobs on Migrate Mate, followed by Langan Engineering and Environmental Services (25) and ARUP Laboratories (2). Across the 10 companies on this list, Migrate Mate is tracking 284 live TN jobs, updated daily.
Who qualifies for TN sponsorship?
TN visa eligibility is limited to Canadian and Mexican nationals applying for roles that appear on the USMCA profession list. Scientists qualify under designated categories such as Scientific Technician, Biologist, Chemist, and related fields. Most qualifying roles require at least a bachelor's degree in a directly related discipline, though some categories accept equivalent professional experience. Applicants must be entering the United States temporarily for prearranged employment with a specific U.S. employer.
Do scientists qualify for TN as a specialty occupation?
Yes. Scientists typically hold a bachelor's degree in a specific field, which is exactly the specialty-occupation standard TN is built around. What matters is that the employer classifies the role under a matching occupation code and that your degree lines up with it.
How do I get TN sponsorship from a top sponsor?
To obtain TN status through a qualifying employer, Canadian nationals present their job offer letter, degree credentials, and proof of citizenship directly at a U.S. port of entry, no advance visa appointment is needed. Mexican nationals apply at a U.S. consulate abroad and receive a TN visa stamp before traveling. In both cases, the employer provides a support letter describing the role, its fit to a USMCA profession category, and the employment terms. TN status is granted for up to three years and can be renewed indefinitely.
