What are immigrant visas and non-immigrant visas?

1. immigrant visa: an immigrant visa is a document issued to foreign immigrants as an entry visa country. Immigrant visas are closely related to green cards. You can get a green card if you get an immigrant visa. The "green card" is not green, but a pink foreigner registration card. The green card proves that the holder can live permanently in the country where he immigrated and has the right to work legally in his country.

2. Non-immigrant visa: Non-immigrant visas are mainly "short-term" or "tourist visit" visas. You are only allowed to make a temporary short-term stay in the United States, although the "short-term" stay may last for several years. The categories of non-immigrant visas are mainly classified according to the main purpose of the applicant's visit to the United States. With a few exceptions, people who come to the United States with non-immigrant visas can only engage in matters related to their visa types in the United States.
