The U.S. visa is a fundamental document for everyone who wants to visit the United States, since there is one for each type of trip and, unless there is some exemption to process it, it will be requested by the authorities to allow arrival at the port of entry.
In the case of Mexican citizens, the Border Crossing Card or BCC can also be used as a valid entry document, as long as all the necessary requirements for it to be accepted are met.
In that context, whether a U.S. visa or BCC is used, it is essential to verify a key piece of information before traveling: the date on which this document was processed, since its validity is limited and the trip will not be allowed if it has expired.
United States airports block the arrival of Mexicans who processed their visa or BCC on this date
Mexican citizens who want to travel to the U.S. will not be able to do so with any U.S. visa or BCC that was processed before August 2016, since the maximum validity of these documents is 10 years.
If this period has ended, the holder will need to update the visa in order to travel.
Verifying this information and confirming that the permit is still valid is essential to avoid any inconvenience with the authorities.
How the U.S. visa should be renewed
The Department of State says that when the U.S. visa needs to be updated, it is necessary to go through the entire visa application process again. However, it is specified that there are certain situations in which a visa applicant may be exempt from the interview when renewing the document. These cases are detailed by each United States Embassy.
Only travelers who qualify for automatic revalidation may reenter for a short period with an expired visa.
What happens if the U.S. visa expiration date coincides with the stay in the country?
Although the visa must be valid at the time of travel, expiring during the stay in the United States is not considered a problem.
