Aliens entering under this classification are considered non-immigrants. TN status is granted for an initial period of up to one year, with subsequent extensions possible. The requirements for Canadians and Mexicans wishing to enter under this classification are not the same.
Canadian citizens have two options.
First , they may have their employer file an I-129 form at the closest regional INS office. This option does not require leaving the U.S. Second, Canadians may return to Canada to re-apply at the port of entry with the same documentation that is required for an original application. End bold statement. Mexican citizens must have their employers renew their labor certification and file another I-129 with their regional INS office in order to extend their stay.
