This link allows you to find out if your US visa has been revoked.

The United States government has implemented measures regarding visa status, including the availability of an online link for individuals to verify if their U.S. visa has been revoked. The U.S. administration maintains the authority to revoke visas at its discretion, a policy currently utilized as part of broader efforts to increase scrutiny in the visa process and address irregular migration.

Simultaneously, the U.S. Department of State has initiated a global pause on immigrant visa applications for permanent residency. This administrative action has resulted in the cancellation of scheduled interviews for applicants, who are being notified of these changes via email.
