Visa validity period

The validity period of a visa refers to the period of time from the date of issuance of the visa to the period after entry is allowed. If this period is exceeded, the visa will be invalid. Generally, countries issue entry visas that are valid for 3 months, and some countries issue entry visas that are valid for 1 month. Some countries have strict restrictions on visa validity. For example, Germany only issues visas based on the application date. Transit visas are generally valid for a short period of time.

Period of stay of visa

Period of stay of visa refers to the time the holder is allowed to stay after entering the country. The difference between it and the validity period of the visa is that the validity period of the visa refers to the period of use of the visa, that is, the holder can enter, exit or pass through the country within the specified time. For example, if a person from a certain country has an exit visa valid for 3 months and a stay period of 15 days, then this visa can enter or leave the country any day within 3 months from the date of issuance. However, from the day of entry, Until the day of departure, the holder can only stay in the country for 15 days. Some countries issue visas that require entry within 3 months, and the stay period after entry is 1 month; in some countries, the entry period and stay period are the same. For example, the validity period and stay period of a U.S. visit visa are both 3 months, that is, it is valid only if you enter the country within 3 months, and you can only stay for 3 months after entering the country. The validity period of a visa is generally 1 month or 3 months; the longest is generally half a year or more than 1 year, such as employment and study visas; and the shortest is 3 days or 7 days, such as transit visa.

The number of times a visa is valid

In addition to the validity period and period of stay, a visa also stipulates the number of times it is valid.
