NON-IMMIGRANT VISAS
Non-immigrant (temporary) visas are generally available to qualified individuals who wish to travel to and remain in the United States for a finite period of time for a specific purpose, such as to study, undertake employment or for business visits.
Most applicants for temporary admission to the U.S., regardless of age, must have his or her own visa, unless they qualify to enter the U.S. for a short trip for pleasure or business under the Visa Waiver Program. Spouses and unmarried children under the age of 21 may apply to obtain a visa to accompany the principal applicant, but usually employment authorization is not granted to dependent visa holders.
