The United States government has implemented a global pause on immigrant visa applications for permanent residency, resulting in the cancellation of scheduled interviews. Affected applicants are receiving notification of these cancellations via email. This action coincides with broader efforts by the current administration to increase scrutiny during the visa issuance process and address irregular migration.

Additionally, the U.S. government maintains its authority to revoke existing visas at its discretion. A digital link has been made available to allow individuals to verify the status of their U.S. visas, providing a mechanism for those concerned about potential revocations to confirm their current standing.
