U.S. Embassies and Consulates have begun a phased resumption of routine visa services.
“[…] U.S. Embassies and Consulates have continued to provide emergency and mission-critical visa services since March 2020 and will continue to do so as they are able.  As post-specific conditions improve, missions will begin providing additional services, culminating eventually in a complete resumption of routine visa services.”
