The sooner you start preparing and gathering your documents, the sooner you can enter the Express Entry pool. For example, you may need information related to travel documents, language tests, educational credential assessment reports, etc.
By starting the process now, you are more likely to have your paperwork in order by July and be in a position to receive an Invitation to Apply for permanent residence (PR) when draws resume in July.
When you submit a profile in the Express Entry pool and select a province of your choice, you will have a double benefit: you can receive a direct Express Entry invitation and also be selected by the province of your choice. Receiving a provincial nomination will give you an additional 600 points toward your CRS score. The increased score will virtually guarantee that you will receive an Invitation to Apply (ITA) for Canadian PR in an upcoming draw.
