Several clinic locations do not alone settle eligibility. Identify the prearranged professional services in the United States, every contracting party and any ownership or control. Canadian or Mexican citizenship and the Veterinarian entry’s credentials must also be established. Have counsel determine which employment relationships and authorizations the actual agreements require.
The structure carries the analysis
A relief veterinarian engaged by a single agency that assigns shifts is a different case from one holding separate agreements with four independent practices. The first can often be presented as one employment relationship; the second involves several. Neither is ruled out in the abstract, but they require different documentation, and deciding which description applies is not something to settle from a schedule alone.
TN concerns qualifying temporary professional activity for Canadian or Mexican citizens in listed USMCA professions. Eligibility follows the duties and the credential, not the employer's title. 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. Decide whether a Canadian applicant will request admission at a port of entry or whether the employer will use Form I-129, then tailor the supporting record to that process. If a task list mixes professional analysis with sales, installation, or general operations, decide whether those secondary tasks are genuinely incidental.
