Start with the TN eligibility and application overview
What the TN rule requires of a nurse
The applicant must be a Canadian or Mexican citizen with a prearranged professional position in the United States. For Registered Nurse the listing permits a state or provincial licence or a Licenciatura Degree, and the employer's letter should identify which qualification is being relied on. Canadians apply at a port of entry or by petition on Form I-129; no visa stamp is needed. Self-employment is not permitted, so a nurse cannot enter TN to run her own staffing agency, and any ownership in the U.S. employer must be disclosed. TD dependants may study but may not work. A first review should make a three-column timeline identifying the issuing body, required record and expiry date for each item. That comparison exposes a mismatched start date early.
The health care worker certificate is a separate gate
Nurses, physical and occupational therapists, speech-language pathologists, medical technologists and physician assistants are subject to a certification requirement before admission in a work-authorized status. The certificate confirms education, licensure and English proficiency through an approved organization. A nurse can hold a valid Saskatchewan licence, a signed offer and a correct employer letter and still be refused at the port of entry because this document is missing or expired. Ask the recruiter on day one whether the hospital has handled this before and which organization it expects the nurse to use. Compare the certificate expiry against the intended admission period. A certificate that lapses before travel should be renewed rather than explained verbally at inspection.
Which licence the letter should cite
A Saskatchewan registration satisfies the listing's provincial-licence wording, so a nurse may qualify for TN status before the U.S. state licence issues. Whether the hospital will let her work without the state licence is an employment question, not an immigration one, and the answer is usually no. Decide with the employer whether the letter will cite the provincial licence with a stated start date after state licensure, or whether the application waits until the state board has issued. Do not let the letter describe a state licence that does not yet exist. A pending application receipt is evidence of effort, not the credential itself. The employer should choose a later start date if its clinical policy requires an issued state licence.
Duration, extensions and the temporary character of the stay
TN admission can be granted for up to three years at a time and extended, but the applicant must intend a temporary stay each time. A nurse who mentions at the border that she plans to apply for a green card through the hospital creates a question about intent that the officer has to resolve. Discuss any long-term plan in the consultation, where it can be sequenced honestly, rather than volunteering it at inspection. Keep the employer letter's dates aligned with the contract and the licence expiry. Keep copies of prior admission records and extension filings with the employment file. A later application is easier to assess when the duties, employer and licence history remain consistent.
