Determine whether only logistics changed or whether the duties, employer or other material terms are now different.
Review the revised facts before relying on the file
A prior assessment should not be treated as permission for every future assignment. Update the account and obtain advice about the process applicable to the actual change.
Set a specific milestone for receiving corrected, consistent documents, and only build the rest of the timeline, including any planned start date, around the confirmed corrected assignment dates. Work backward from the employer’s last workable start date, allowing time to obtain the contract, citizenship proof, and the credential evidence required by the selected USMCA profession. A first review should produce a sequence: resolve the professional match, collect the executed terms, select the procedure, and travel only when the record supports the request. TN is granted for a period not exceeding three years and can be extended or a new admission sought, but each renewal is decided on the duties as they then stand, which on a long construction project are rarely the duties described at the outset.
