Incomplete or unverifiable records generally aren't enough, since the credential needs to clearly and verifiably match the profession's requirements. Filing or traveling with gaps still open risks the application, or the entry itself, being questioned on grounds that could have been resolved beforehand.
Close verifiable gaps before relying on the credential
A credential that can't currently be verified isn't the same as one that doesn't exist; the fix is usually obtaining authentic replacement records, not abandoning the claim. Identify precisely what's unverifiable, a missing transcript, an unclear program name, and pursue the actual institution for correction before treating the credential as ready to support a filing. Two conditions run alongside the credential and are worth confirming in the same conversation, since a resolved records problem is of no use if either fails.
The employment must be prearranged with a United States employer or entity, because the category does not permit an applicant to work for their own account, and the applicant must be a citizen of Canada or Mexico. Establish citizenship from the passport rather than from how the applicant describes their status, since permanent residence in Canada does not satisfy that requirement however long it has been held, and discovering it late wastes the entire records exercise.
