in airline tickets when arriving by air). The U.S. immigration officer will then adjudicate the application on the spot and grant or deny TN status. If the decision is to grant TN status, the Canadian enters the U.S. and begins TN employment. If the decision is to deny, the immigration officer will often detail the shortcomings in the application; if these are relatively straightforward to correct, the Canadian will often correct the problem soon thereafter and then return to the border to reapply. Applying with the USCIS Alternatively, a prospective TN employer can petition USCIS for a foreign national to be either: (a) accorded TN status immediately upon petition approval, by change of status or (b) to be effectively pre-approved as TN-eligible for that specific position, with TN status for the new job to take effect upon the individual next being admitted into the United States at a U.S. port of entry. The procedure for doing this is by submitting Form I-129 petition with a US$460 fee to the appropriate (California or Vermont) USCIS service center. For option (a) above, USCIS would send a notice approving the petition, along with a Form I-94 reflecting the change of status (or extension of stay, if the worker is already in TN status). For option (b) above, if USCIS approves Form I-129, the prospective worker may then come seek admission from a CBP officer to the United States as a TN nonimmigrant by providing the following documentation at a U.S. port of entry or at a designated pre-clearance/pre-flight inspection station: Proof of Canadian citizenship; and Approval notice from USCIS for Form I-129. In addition, when applying for admission, the applicant should have in their possession a copy of the Form I-129, and all supporting documentation that was submitted to USCIS, in order to respond to any questions about eligibility. The applicant should also be prepared to pay any applicable inspection fees at the time that he or she seeks admission. If a CBP officer finds the applicant to be eligible for admission, the person will be admitted as a TN non-immigrant. Domestic partner/cohabitating partners A TN visa holder may be able to bring their unmarried domestic partner to live with them. A non-Canadian citizen domestic partner can apply for a B-2 or B-1/B-2 visa from a U.S. consular post, and if issued, seek admission in B-2 classification for up to one year. The
