Lawful Permanent Residency (Immigrant Visas)
While a non-immigrant visa allows foreigners to enter the United States for a limited period of time, a U.S. green card grants foreigners authorization to live and work on a permanent basis, as a Legal Permanent Resident. Though the majority of individuals gain legal permanent resident status through sponsorship by a family member or employer in the U.S., others can gain this status through refugee or humanitarian programs.
