Explain the actual professional responsibilities, circumstances when the worker is called and relevant pay and duration terms.
Clarify what happens between assignments
A generic job posting may not explain the arrangement. Ask the employer for facts about this offer, including other duties expected, rather than omitting inconvenient responsibilities.
A Canadian citizen may apply for the classification at a US port of entry or preclearance location, presenting proof of citizenship, the employer's support letter, the degree and transcript and the applicable fee, or the employer may file Form I-129 in advance with USCIS. The employer's support letter, the original credential the profession requires, proof of Canadian citizenship, and any agency or client agreement that explains where the work will physically happen. Bring a passport confirming citizenship, the job offer with a detailed duty description, transcripts and licences, a resume covering relevant experience, and any existing U.S. immigration history. If the recruiter drafts a letter saying the position is contingent on licensure, ask for it to be reissued once the licence is granted, because a contingent offer invites the officer to ask whether employment really exists. Expedited passport service shortens one queue and does nothing for a birth certificate held by a foreign registry, a transcript that must be reissued, or an employer letter waiting on a signature abroad.
