What kind of visas do American marriage immigrants belong to?

Hello, the following questions are answered by Aussie immigrants from Guangzhou:

Marriage immigrants are suitable for people who have spouses in China or other countries in the United States (they can be American citizens or American green card holders).

American CR 1 Marriage Immigrant Visa: It is applicable to spouses who have been married to American citizens for less than two years, and their unmarried children under 2 1 are CR2 visas.

American IR 1 Marriage Immigration Visa: It is applicable to spouses who have been married to American citizens for two years, and their unmarried children under the age of 2 1 are IR2 visas.

I hope it helps you.
