The NAFTA trade agreement created a non-immigrant category for Canadian and Mexican professionals to enter the US and work. Like the H-1B, it is for professional positions which must require a minimum of a Bachelor’s degree in a specific field, and the individual must have the specific degree. Although the TN applies to Mexican citizens, it is of little practical value, as the same processing steps must be followed as for an H-1B. Therefore, UCONN uses the TN almost exclusively for Canadian citizens (“landed immigrants”, the Canadian equivalent of permanent residents, do not qualify). This is a temporary status and TNs should not intend to immigrate. The main advantage of TN status is that no prior INS processing is necessary; the Canadian can get the classification at the border.Please be advised just asTN’s are Employer Specific (work authorized only by sponsoring employers) only TN’s sponsored by UCONN can be paid by UCONN for compensition and only through the Payroll Department. No Honorarium can be paid by UCONN to a TN Visa holder from another University.
