On Mar. 26, 2020, the U.S. State Department announced:
We encourage medical professionals with an approved U.S. non-immigrant or immigrant visa petition (I-129, I-140, or similar) or a certificate of eligibility in an approved exchange visitor program (DS-2019), particularly those working to treat or mitigate the effects of COVID-19, to review the website of their nearest embassy or consulate for procedures to request a visa appointment.
Each U.S. Embassy or Consulate has procedures for emergency appointments, usually posted on their website or that of the contractor that helps them schedule appointments.
Our law firm is helping medical professionals and others with an emergency need to apply for visas, during this time that routine visa services are suspended.
