An individual who wishes to enter the United States and remain on a temporary or permanent will require a visa. Non-immigrant visas are more appropriate for temporary visits. The type of non-immigrant visa which an individual needs depends on the purpose of the temporary stay. There are non-immigrant visas which fit a particular purpose, such as education or religious duties. It is important to choose the non-immigrant visa which most closely reflects the individual’s purpose for being in the United States, as their ability to engage in other activities may be restricted. For permanent stays, a relative or employer can sponsor an individual.
