Immigration is a process where a foreign individual moves to United States on a temporary basis or to live permanently. For a person to enter United States whether for a temporary visit or a permanent stay, a visa is required. A visa is a permit card for a non–citizen to travel or enter United States. A visa does not authorize a person to enter United States. Instead it permits the person to travel to United States. The entry into United States will be decided by the inspectors of Department of Homeland Security (DHS) , Customs and Border Protection (CBP) . These visas are classified into Immigrant Visa and Non- immigrant visa. Immigrant visas are used by people who wish to live permanently in US and Non- immigrant visas for people who wish to travel to United States on a temporary basis for business or for pleasure.
