Yes, a US visa can be cancelled even after it has been approved and issued. This can happen at various stages, including before travel, on arrival at a US port of entry, or even after you have entered the country. Here are some common reasons why a US visa might be cancelled after approval:

1. New Information or Changed Circumstances

If the US authorities receive new information suggesting that you no longer qualify for the visa (for example, academic misconduct, criminal records, misrepresentation in your application, or security concerns), your visa may be revoked.

2. Violation of Visa Terms

If you violate the terms of your visa (such as working without authorization on a student visa, or overstaying your allowed duration), your visa can be cancelled.

3. Administrative or Technical Reasons

Sometimes, administrative errors or updates in the law or visa policy can also lead to visa cancellation.

4. Visa Cancelled at Port of Entry

The US Customs and Border Protection (CBP) officer at the airport or border has the authority to deny you entry and cancel your visa if they find any discrepancies or inadmissibility issues.

5. Security Checks

If your name appears on a security watchlist or there are concerns related to national security, your visa can be revoked.

6. Failure to Maintain Student Status

For students (F-1, J-1, etc.), failure to maintain full-time enrollment or comply with SEVIS requirements can result in visa cancellation.
