A summary of these entry conditions is presented here: https://www.office-tourisme-usa.com/preparez-votre-voyage/formalites-dentree/
Information is updated daily and to this day, these measures are still valid.
Since February 12, 2022, proof of vaccination has again become sufficient to come/return to France, regardless of the country of origin. A negative test is no longer required if the traveler is completely vaccinated (2 doses of vaccine, third dose compulsory no later than 9 months after the second dose). For unvaccinated travellers, the obligation to present a negative test to travel to France remains. The measures on arrival – testing, isolation – are lifted when coming from countries on the green list. Finally, non-vaccinated people from a country on the « orange » list (which the USA are currently part of) must continue to present a compelling reason and may still be subject to a random test on arrival.
It is currently possible to get tested for free or for very a small fee in all United States. Here is a link where you can find all places that offer free testing, State by State: https://www.hhs.gov/coronavirus/community-based-testing-sites/index.html
And since December 6, 2021, the American Government is asking all travelers over 2 years old arriving in the United States, a negative test dating less than 24 hours before departure, whether these travelers are vaccinated or not. We therefore invite all French travelers to perform a viral screening test (PCR or Antigen) within 24 hours before their departure, whether they are leaving from France or from another country. If the traveler has recently had COVID, official proof of recovery within 90 days will be required. In addition, a certificate certifying that this information is correct will be requested from all passengers.
