Visa Information

Some international visitors will need to obtain a visa for travel to the U.S. The latest official information on visas for foreign citizens can be found on the U.S. State Department website. Since the visa process may vary from country to country, it is best to start the process as early as possible to be able to satisfy all requirements and paperwork.
