What is the meaning of im- 1 on the Canadian immigrant visa?

This is the first one-time visa for permanent residents to land in Canada. After that, you will get a green card and enter and leave Canada according to the requirements of the green card, which can lay the foundation for applying for citizenship. Visa refers to the procedure of endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to show that they are allowed to enter, exit or transit. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country's entry-exit administration (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens.
