Who is eligible for an FB2 Visa category?
To be eligible for an F2B Visa, your immediate family members need to meet the legal definition of “child”. They can still be 21 years old, but they must be unmarried. If they get married before the petition is approved, their application will be revoked. If your children are under the age of 21, they can also fall into the F2A visa category for dependents of U.S. permanent residents.
Once they get their visa, your children will be allowed to live, study and work in the U.S. as permanent residents.
