A non-immigrant visa application is the paperwork and means by which a citizen of a foreign country applies for a non-immigrant visa. A non-immigrant visa is a visa issued by the U. S. government that allows foreigners to enter the country for a temporary stay of specified length.
These visas are generally issued to visitors, tourists, students and people here for business on a temporary basis. The numerous categories of non-immigrant visas are determined by the purpose of the visit. Once the specified time has expired, the visa must be renewed or the visitor must leave the country. Some countries participate in the Visa Waiver program that allows citizens of participating countries to enter the U. S. for up to ninety days without a visa if certain criteria are met.
