Identify the records needed to establish the applicable qualification. An earlier credential may be relevant even when a later one is more advanced.
Explain the academic sequence
Keep the fields and dates accurate. Do not relabel a multidisciplinary programme as a different degree to match the proposed occupation.
Prepare a factual description of the position, the pay and period, and the identity and qualification records the applicant relies on, and resolve any meaningful difference between the offer and any supporting letter before it is finalized. Build the file from contemporaneous records: a detailed employer letter, agreement or offer, itinerary where useful, credential evidence and proof tying the signer to the engaging entity. The listed profession is proved by the employer’s support letter, which should name the appendix occupation, describe the duties in plain terms, state the remuneration, give the period of the engagement and identify who supervises the work. Credential proof comes from the awarding institution or the licensing body, and citizenship comes from a citizenship document; a letter asserting that someone holds a degree proves nothing about the degree. If the degree was earned at an institution outside the three USMCA countries, obtain a credential evaluation from a reliable service before applying, since the regulation requires it and a port-of-entry officer cannot supply it.
