The main types of visa validity are as follows:
1. Single valid visa
This means that visa holders can only enter the issuing country once during the validity period of the visa. For example, if a tourist obtains a single valid tourist visa for a certain country, they can only travel to that country once within the validity period specified in the visa, such as 3 months. Once leaving the country, the visa becomes invalid and cannot be used to re-enter the country again. This type of visa is usually suitable for short-term travel, single business visits, and other situations.
2. Two valid visas
Visa holders can enter the visa issuing country twice within the validity period of the visa. For example, some countries may issue two valid visas to business people, making it easier for them to enter and exit the country twice during a certain period of time for business negotiations, inspections, and other activities. The time for two entries needs to be within the validity period specified in the visa, and there may be other restrictions, such as limitations on the duration of each stay.
3. Multiple valid visas
Multiple entry visas allow visa holders to enter and exit the issuing country multiple times during the visa validity period. This visa is very convenient for people who frequently travel between two countries. For example, a work visa may be a multiple entry visa that allows workers to frequently travel between their home country and the country where they work during the contract period; Some long-term business visas, family visit visas, etc. may also be multiple valid visas. Multiple valid visas can be further divided into:
Limited number of multiple visas: Specific entry and exit limits will be set. For example, multiple valid visas issued by a certain country indicate “5 times”, which means that visa holders can enter and exit the country up to 5 times during the validity period.
Unlimited multiple visas: During the validity period of the visa, the holder can enter and exit the issuing country according to their own needs without any limit on the number of times. However, even with this type of visa, there may be restrictions on the duration of stay and other conditions upon each entry.
