The United States government has implemented a global pause on immigrant visa applications for permanent residency, resulting in the cancellation of scheduled interviews for applicants in the Dominican Republic and elsewhere. Affected individuals are receiving notification of these cancellations via email as the State Department adjusts its processing operations.

Simultaneously, the U.S. government has reiterated its authority to revoke existing visas at its discretion. This measure is part of a broader administrative effort to increase scrutiny during the visa issuance process and address concerns regarding irregular migration.
