Temporary Work visas
A temporary worker visa is a nonimmigrant visa for individuals who wish to work temporarily in the United States. There are several categories ("classifications") of temporary worker visas. Some of these classifications have annual limits. The applicant’s qualifications, type of work to be performed, and other factors determine what type of visa is required under U.S. immigration law.
