I have a visa for business travel to India (I'm a US citizen), but I have been unable to find a definitive statement of whether a COVID-19 vaccination is required for entry. Most of what I've seen on the consulate website is that the vaccine is suggested, and it appears that as of January 2023 you may randomly be required to provide a negative PCR test when you arrive and show a negative test result.
However, I haven't seen any statement that clearly says whether the vaccine is required or not required. A co-worker says that you need a vaccine and a booster, but I haven't been able to confirm that with any official source. Can anyone provide a link to a government website that shows a clear statement of the requirements?
