what is multiple entry visa

A multiple-entry visa is a travel permit that allows the holder to enter a country multiple times during the visa's validity period. This is in contrast to a single-entry visa, which allows only a single entry. Multiple-entry visas are typically valid for a longer period, such as 1, 2, or 5 years, and may have a limit on the length of each stay. Some multiple-entry visas allow for a specific number of entries, such as double or triple entries. The U.S. 10-Year Multiple Entry Visa, for example, allows holders to engage in business and tourist activities within the U.S
