“Monday’s presidential proclamation temporarily restricts certain categories of visas from being issued to protect jobs for American workers while our economy recovers from the effects of COVID-19. This does not affect those currently working in the U.S. on valid H-1B or similar visas. The proclamation also does not prevent individuals in possession of valid visas prior to the effective date of the proclamation from entering or re-entering the country, if they have been abroad, provided they have not otherwise rendered themselves inadmissible.

The U.S. will continue to honor these already valid visas as we help American workers get back on their feet.” – USCIS Deputy Director for Policy Joseph Edlow
