Degrees, transcripts, and any regulator-issued licence or registration serve both files, but often in different forms. Licensing bodies frequently demand verification sent directly by the issuing institution, while a TN review works from the applicant's own copies and the employer letter.
Build one document set with two delivery paths
List each record, who needs it and the required format. A licensing regulator and an immigration procedure can impose different documentation rules. For TN, a degree from an institution outside Canada, Mexico and the United States requires a reliable foreign-credential evaluation. Check the regulator’s requirements separately, and distinguish each evaluation from any language translation.
Substitute the best available records: the employment contract, pay stubs or tax slips, work samples with dates, and a declaration from a former supervisor, together with a short explanation of why the letter could not be obtained. The qualification is proved by the instrument the entry names, with the regulator’s own confirmation where a licence is the basis. Assemble the diploma, transcripts, translations where needed, evaluation methodology, and any licence or experience proof demanded by the particular USMCA profession. Whichever path is used, the applicant should be able to explain the duties, the qualification and the employer chain without reading from the letter, and should carry originals rather than photographs.
