The immigration step is rarely the slow part. Credential equivalency assessments, state licensing and certified civil documents each have their own processing times and should be started first.

Hypothetical example: Once the required records are listed, the next step is to write a processing time beside each one and start with the longest. Equivalency assessments and licensing applications commonly take the most time and depend on third parties who will not be hurried. Certified copies of civil documents can be slow where the issuing authority is outside Canada.
Corporate records that need to be brought current require professional help and the cooperation of other shareholders, which introduces its own delay. By comparison, drafting the employer letter and organising the presentation are short tasks that a household can complete quickly once the underlying documents exist. Sequencing the work this way means the file is complete on the earliest possible date, rather than complete except for the item nobody started.
