The TN or Trade NAFTA Status was authorized by the North American Free Trade Agreement and is only applicable for Mexican and Canadian nationals. Only certain occupations qualify for TN status.
As described above, only Mexican and Canadian nationals qualify for TN Visas.
There are no Visa Quotas associated with TN Visas.
Spousal and Dependent Work Authorization
Spouses do not qualify for work authorization under the TN program.
TN Visas are ordinarily granted for up to three years at a time and can be extended indefinitely. Holders of TN status should note that immigration officials are often unwilling to extend TN Visas beyond 5-7 years under the belief that TN Visa holders who are in the United States for long periods of time ought to seek U.S. Permanent Residency.
