US immigration law allows some non-citizens, who are family members of US citizens and lawful permanent residents, to apply for a Green Card and become a lawful permanent resident themselves.
Immediate relatives – such as a spouse, an unmarried child under the age of 21, or a parent of a US citizen who is 21 or older – can apply, as can widows or widowers of US citizens. There are also other categories of family member eligible to apply:
- Unmarried sons and daughters (aged 21 and over) of US citizens – F-1
- Spouses and unmarried children under 21 of lawful permanent residents – F-2A
- Unmarried sons and daughters (aged 21 and over) of lawful permanent residents – F-2B
- Married sons and daughters of US citizens – F-3
- Brothers and sisters of US citizens (if the US citizen is aged 21 or over) – F-4
