Obtain the source records and ask the evaluator and translator what each needs to correct the discrepancy. Their work may be coordinated rather than follow one universal order. Resolve the material qualification description before finalizing the employer letter, and check any mandatory evaluation requirement rather than treating the report as merely useful.
Let the slowest record set the schedule
Registrar turnaround is outside the applicant's control and can be the longest step, particularly where the institution is abroad or the programme has been restructured. Request those copies before anything else and follow up in writing. Avoid committing to a start date with the employer until the records that support the credential claim are in hand and have been reviewed.
The petition route has the employer file Form I-129 with its base fee and, unless the employer is exempt, an asylum-program fee, and most employers add premium processing to obtain action within the service window. A Canadian may apply at a port of entry or have the employer submit Form I-129; the evaluator's delivery date cannot establish status. The usual timing error is keeping the planned start while leaving a material scope review until after travel.
An evaluation waits on the transcript arriving first, and then on the evaluating service.
