What is Visa Expiry Date?

The visa expiry date is shown on the visa. Depending on the alien’s nationality, visas can be issued for any number of entries, from as little as one entry to as many as multiple (unlimited) entries, for the same purpose of travel. This generally means the visa is valid, or can be used from the date it is issued until date it expires, for travel for the same purpose, when the visa is issued for multiple entry.

This time period from visa issuance date to visa expiry date as shown on the visa, is called visa validity. If you travel frequently as a tourist for example, with a multiple entry visa, you do not have to apply for a new visa each time you want to travel to Thailand.

The visa validity is the length of time you are permitted to travel to a port-of entry in Thailand to request permission of the immigration officer to permit you to enter Thailand. The visa does not guarantee entry to Thailand.

The Expiry Date for the visa should not be confused with the authorized length of your stay in Thailand, given to you by the immigration officer at port-of entry. The visa expiry date has nothing to do with the authorized length of your stay in Thailand for any given visit.

Each time you arrive at the port-of-entry, an immigration officer decides whether to allow you to enter and how long you can stay. Only the immigration officer has the authority to permit you to enter Thailand.

HOW CAN I KNOW? 
Misunderstanding of permission of stay.

The date of validity indicates that the visa must be utilized by entering Thailand within the period. Then the holders will receive an initial stay of 90 days from the date of arrival. Students should check visa expiration date stamped upon the arrival, not the one stamped by the Embassy or Consulate.
