A visa is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or leave its territory. Visas typically include limits on the duration of the foreigner’s stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual has the ability to work in the country in question
You will acquire a visa when entering a foreign country from the United States. The visa should be carried with your passport while in a foreign country. You will need to have the visa with you as you exit the foreign country. The visa will be purchased prior to going through the foreign country’s immigration. If flying, the visa cost is usually included with the airline (airfare) fees. If driving, it will need to be purchased at the border; approximately $40 USD. You may need to surrender your visa upon exit from a foreign country.
