There are two parts to the application process:

Your application to NNAS could take up to 12 months to complete. This depends on:
When NNAS receives all your required information and documents.
When you successfully complete a language proficiency test, if required.
When your documents are translated, if required.
Your application is active for 12 months. If your file is incomplete after a year, you must send a letter to request that it be re-activated, and pay a fee. See Fee Schedule.
Once you receive your Advisory Report, you can then apply to the regulatory body in your chosen Canadian province. Each regulatory body has its own registration requirements and timelines. These depend on whether you require another assessment or courses to meet their eligibility requirements. It could take another year or more for the regulatory body to make its decision.

Each time NNAS receives a document, your application status on your online account will be updated, and NNAS will let you know what documents are still needed to complete your file. You will also be notified by email.
