You may apply in person at selected post offices, at federal or state courts of records, or at one of the passport agencies of the U.S. Department of State. A visa is written permission to visit a country granted by the government of that country. If you plan to study in a country for an extended period, you may need a special student visa. Information relating to visas may be obtained from the nearest embassy or consulate of the country concerned. Some embassies and consulates process visa requests quickly, but many do not.
Adequate insurance is important when visiting another country.
Before leaving the United States, be sure that your medical and accident insurance policies are valid while traveling abroad. You should verify that your coverage includes medical evacuation and repatriation. A physical and dental checkup are advised, and you should obtain any special vaccinations and inoculations that may be required or recommended. Once you have selected your program, prepare for life in a foreign country. If you are going on an organized program, you will probably receive much useful information and guidance at predeparture orientations.
