IN THIS GUIDE · Plan a physiotherapist’s TN around its three-year admissions, renewals and the temporary-intent question
Start with the TN eligibility and application overview
Three years at a time, with no numeric cap
A TN professional is admitted for the period of the engagement stated in the employer letter, up to three years. Unlike L-1, the regulation sets no maximum number of years in TN status. Renewal is by a new application at a port of entry with a new letter, or by the employer filing Form I-129 for an extension before the current period ends. Each renewal is decided as if it were a first application: citizenship, the listed profession, the credential and the prearranged professional engagement are examined again. For the physiotherapist that means keeping the state licence current, because the officer will look for it, and asking the employer for a fresh letter with a new end date each time.
Temporary intent is tested at every entry
TN is a nonimmigrant classification, and an applicant must intend to remain temporarily, meaning for the period of the engagement, with no immediate intention to abandon foreign residence. Long renewal histories are not by themselves disqualifying, but an officer may ask what ties remain to Canada and whether a pending immigrant petition changes the picture. A physiotherapist who has held TN for six years and has just been sponsored for a green card by her employer faces a real question at the next renewal, since TN does not carry the dual-intent tolerance that H-1B and L-1 enjoy. Planning a permanent route means timing the change of status so that the TN renewal is not the moment intent is tested.
Events that end a TN before the date
TN status is tied to the employer named in the letter. If the practice is sold to a new legal entity, if she moves to a different clinic, or if her duties change from physiotherapy to management, a new TN application or an amended petition is required before she continues working; the original admission does not follow her to a new employer. If the employment ends, a grace period of up to sixty days or until the admission expires, whichever is shorter, allows her to depart or change status. The state licence is a separate clock: an expired licence does not end the immigration status, but it ends the professional work the status permits.
Health-care certification and the state licence
A physiotherapist admitted to work in the United States must also present a health-care worker certification from an approved credentialing body at each admission, in addition to the professional credential, under the regulation that governs health-care occupations. The certification has its own validity period and must be current at renewal. The state licence is issued by the state licensing board on its own timetable, and she should hold it, or an authorization to practise pending licensure that the state recognizes, before the start date in the letter. A TN application filed with a degree but without the certification will be refused, and an employer letter dated before the licence issues should give a start date after it.
