Family members of U.S. citizens or lawful permanent residents who hold Green Cards can join their relatives in the United States through the USA Dependant Visa. Dependents need to choose among F-2, H-4 or L-2 visa categories according to the primary visa holder's immigration status. These visas enable dependents to live, study, and sometimes work while residing in the United States. The primary objective of these visa types stands to bring families together although each category maintains particular requirements for eligibility.
