One of the hallmarks of the Canadian Immigration system, and Canadian Society as a whole, is that we value prospective immigrants like you and your family. Canada bring hardworking people into country and reward them with Canadian Permanent Residence (PR). A Canadian PR Card, which is similar to a US Green Card, allows the holder to live anywhere in Canada and work in any job they wish. It is also a gateway to Canadian Citizenship!
The Express Entry system is a new way that Immigration, Refugees and Citizenship Canada (IRCC) is managing the intake of applications for the Federal Skilled Worker program, the Federal Skilled Trades program and the Canadian Experience Class program as of Jan 1st, 2015. Processing times to receive your Canadian Permanent Residence Visa under Express Entry are quoted as low as 6 months!
In brief, applicants submit an Expression of Interest form to IRCC summarizing their skills and credentials. Following submission, applicants are entered into a pool of individuals with similar career backgrounds. Whether you rank higher or lower in your pool will completely depend on how you present your initial application. The highest ranking candidates will periodically be pulled from the pool and invited to apply for Canadian Permanent Residence.
