Review the current offer and intended activity before relying on the earlier account. The effect depends on what changed and the actual procedural stage.
Keep an accurate revised schedule
Retain the employer’s amendment and explain whether the role, pay or duration changed. A prepared letter should not remain in use if it no longer describes the work.
Allow time for the evaluator to review the foreign program, request any missing records, and issue a report, then time for the employer to confirm whether licensing applies. Employment letters from former employers, certified credentials and a properly drafted offer letter are the slow parts, and an advance petition adds processing time that varies. Because admission is decided on arrival and the period granted is tied to the employment described, applying against a schedule that has not settled produces either a refusal or an authorization that no longer matches the work. Request the corporate and governance documents at the same moment the offer is received, not after the professional qualification has been confirmed, because those two enquiries run in parallel and only one of them depends on another organisation's cooperation.
