President Biden will ease foreign travel restrictions into the U.S. beginning in November, when his administration will require all foreign nationals flying into the country to be fully vaccinated as well as providing proof of vaccination before boarding, as well as proof of a negative COVID-19 test taken within three days of flight. Biden will also tighten testing rules for unvaccinated American citizens, who will need to be  tested within a day before returning to the U.S., as well as after they arrive home.  The Centers for Disease Control and Prevention will also require airlines to collect contact information from international travelers to facilitate contact tracing.
