Read the general professional work overview
Highlands applicants moving an existing work arrangement from Canada should identify the actual US engagement and the permission it requires. For health professions, one document decides more than the offer does. A medical laboratory technologist, like a nurse, is subject to the health-care worker certification requirement at admission, so the applicant must decide to start that certification well before accepting a start date.
State the current proposal
Describe employer, duties, remuneration and duration. Explain material differences from prior work in Canada rather than assume an old contract answers every US employment question.
Apply TN requirements
Canadian or Mexican citizenship, a listed USMCA profession and its particular qualifications remain necessary. Years of familiar work do not independently establish eligibility or current US authorization.
Review ownership and procedure
Sole or controlling ownership of the US enterprise receiving services raises prohibited self-employment. Canadians generally may seek visa-exempt TN admission; Mexicans generally need a visa, with petitions where appropriate. An unchanged pay account does not decide permission to work.
Hypothetical example: a laboratory technologist’s certification
Hypothetical example: a Highlands medical laboratory technologist is offered a position by a US hospital laboratory. Medical laboratory technologist is a listed USMCA profession requiring a bachelor’s degree or a post-secondary diploma plus three years’ experience. The hospital’s letter covers duties, pay and duration, and she has the diploma and experience. What decides admission is the health-care worker certificate issued by an approved credentialing body, which verifies her education, licensure, English proficiency and any required examination; without it a TN applicant in a covered health occupation is inadmissible even with a perfect offer. Certification can take months and depends on transcripts the Canadian institution must send directly. Any state laboratory-personnel licence is a further, separate requirement. The order that works is: begin certification, request transcripts, confirm state licensing, then finalize the start date with the employer. A start date agreed first and certification started second produces a delayed or refused entry.
Remaining conditions to keep straight
Canadian citizenship remains the threshold, and a permanent resident cannot use TN. The hospital, not the applicant, must be the enterprise receiving services, so any proposal to work through her own company should be avoided. Canadians apply at the port of entry or by I-129 and need no visa; TD dependants who are not Canadian citizens need a consular TD visa, and no TD dependant may work. Bring originals of the diploma, experience letters and the certificate.
