A visa is a document issued by the authorities of a country to a foreigner to travel to the territory of a State of which he or she is not a citizen. The VISA is mandatory for anyone wishing to enter and stay for a limited time in a territory. However, it is not uncommon for customs or border police in a state to prohibit entry to an individual who is in possession of a valid visa. The visa is illustrated by a stamp, sometimes a sticker affixed in the applicant's passport. It is usually issued by a diplomatic or consular authority, such as an embassy, and by the border police of the destination country.
Once the visa has been granted, it usually indicates the date of issue, the issuing authority, the duration of the beneficiary's stay, the reason for travel, the period of validity and the territory concerned. Visa has been introduced by many countries to control immigration.
However, for reciprocal reasons, some States have the possibility of imposing a visa on their nationals to enter friendly territory. There are many types of VISAs available to travel to the United States. The latter have different characters and goals.
Depending on the purpose of your trip, apply for an appropriate visa. For an internship, an employee, to study or to invest, you will need a different type of visa. To obtain your VISA you will need to complete an application, provide a large number of supporting documents and be interviewed at the U. S. Embassy.
Once on American soil, you can still be turned back at the entrance to the USA. Take your disposition and prepare yourself properly not to miss the last step before the summit.
