What age can you apply for green card?

There are many different Green Cards, therefore the age eligibility is also different. For unmarried adults, who have at least one US citizen parent, they must be 21 years of age or older. F2A applicants (spouses and unmarried children of a green card holder), the children must be younger than the age of 21 and F2B applicants (unmarried children of a green card holder), should be older than the age of 21.
