What is Visa Expiration Date?
Visa Expiration Date meaning The visa expiration date is shown on the visa. This means the visa is valid, or can be used, from the date it is issued until the date it expires, for travel for the same purpose, when the visa is issued for multiple entries. This time period from the visa issuance date to visa expiration 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 the United States. As an example of travel for the same purpose, if you have a visitor visa, it cannot be used to enter at a later time to study in the United States. The visa validity is the length of time you are permitted to travel to a port-of-entry in the United States to request permission of the U.S. immigration inspector to permit you to enter the United States. The visa does not guarantee entry to the United States. The Expiration Date for the visa should not be confused with the authorized length of your stay in the United States, given to you by the U.S. immigration inspector at port-of-entry, on the electronic I-94 admission stamp or paper Form I-94, Arrival/Departure Record. The visa expiration date has nothing to do with the authorized length of your stay in the United States for any given visit.
