Countries that issue entry visas are categorized into two types: Single Entry and Multiple Entry. A Single Entry visa allows you to enter the country only once, while a Multiple Entry visa allows you to enter the country multiple times within the validity period of the visa.

Single Entry – This type of visa allows you to enter a country only once during the visa’s validity period. If you leave the country, you will need to apply for a new visa to re-enter.

Multiple Entry – This type of visa allows you to enter a country multiple times. With this visa, you can enter the country as many times as you wish within the visa’s validity period.

Each country has its own regulations for issuing visas. The type of visa issued, eligibility, validity, and duration of stay can vary.

Visas can be issued directly from another country, through a consulate, or through an embassy in the applicant’s home country.
