family members of Mexican TN-2 visa holders and to non-Canadian family members of Canadian TN-1 entrants. Canadian citizens For Canadians, TN status does not involve a visa. Canadian professionals are admitted into the United States in TN-1 status at the border. Canadian citizens are not required to obtain a visa, but instead receive TN status with U.S. Customs and Border Protection (CBP) at their port of entry (most commonly it is done upon entry to the United States from Canada, but entry in TN status is permitted at any port of entry, such as an airport with United States border preclearance). The TN status will only be granted if the period of stay is temporary. There is no appeal recourse if one is refused TN status. Canadian citizenship for TN status purposes may be by descent or grant (naturalization). Those with educational qualifications from sources outside Canada or the U.S. must prove equivalency to the U.S. requirements. Canadians have two alternative procedures to apply for TN status. One is by going directly to a U.S. port of entry or Canadian airport with U.S. preclearance facility, and the other is by the filing of a Form I-129 petition by the employer to the designated processing office prior to their intended trip into the United States [two- six months processing time, unless you use the Premium Processing service]; Canadians already in the U.S. could do the same, without having to leave. Directly to a port of entry Applying for this status is a fairly streamlined procedure. The Canadian, arriving at the U.S. port of entry no more than the 10 days before the job start allowed by federal regulations, must: Request TN status; Present a proof of a job offer from a U.S.-based employer, in the form of an employment letter detailing a temporary employment for not more than three years; If the job offer documentation does not contain sufficient detail, present a letter addressed to the CBP by the employer asserting the bases on which the offer (and the individual's credentials, to the extent relevant) make that person eligible for TN status; Bring the original documentation and provide a copy of the applicant's college degree and employment records which establish qualification for the prospective job; Present a proof of Canadian citizenship (passport); and Pay a fee of US$50 (plus an additional $6 at a land or sea crossing; this is included
