Is there a high chance of staying after applying for a postdoc in Canada?

It depends on what major you studied for your PhD. If you apply for a Canadian green card, the easier way than the United States is skilled immigration, which meets the 38 occupational requirements released by the Canadian government (for example: finance, computer information system management, doctors, nurses, mechanical operators, plumbers, electricians, University professors or college teachers, etc.), it is easier to apply if you have good academic qualifications and foreign languages; or you can apply for a Canadian green card after one year of working in a Canadian company that accepts you after studying in Canada. These two categories are for those in short supply in Canada. Professionals and international students are the priority ways to apply for green cards. For reference only.
