Collect the credential evidence relevant to the TN profession and separately identify any licence, verification or certification needed for the intended activities. Record the issuing authority, current status, restrictions and expiry date. A Canadian professional registration should not be described as a U.S. licence.
Keep the purpose of each document visible
Ask the employer and regulator which records establish eligibility to practise and which steps remain outstanding. For example, a receipt confirming that a licensing application was submitted is not necessarily proof of approval. Preserve official correspondence explaining any conditions and check that it concerns the actual role and jurisdiction.
Where translation or third-party verification is required, follow the applicable authority’s instructions. This is a method for organizing evidence; it does not declare a universal licensing attachment list for every TN profession. Keep two files and label them by purpose, since the same document can be relevant to both processes for different reasons and mixing them causes confusion in both directions.
The immigration file holds citizenship evidence, the academic credential and the employer's description of the position. The licensing file holds whatever the board requires, which commonly includes verified transcripts sent directly by the institution, verification of any existing registration sent directly by the issuing regulator, examination results, and sometimes a credential evaluation prepared to that board's own specification. Note that boards frequently require documents sent directly rather than by the applicant, which takes longer, and that an evaluation prepared for one purpose may not satisfy another.
Record for each document which process it serves and who must send it.
