On April 30, 2021, U.S. President Joseph R. Biden issued a proclamation suspending the entry of certain nonimmigrants from India due to the widespread, ongoing person-to-person transmission of COVID-19 in that country. Starting 12:01am (EST) on May 4, 2021, travelers who were physically present in India during the 14-day period immediately preceding their entry or attempted entry will not be able to enter the U.S. unless they qualify for an exemption. The proclamation and travel ban will remain in effect until terminated by the president.
