International Travel- US re-entry requirements

So we are going to Europe in 3 weeks. Just learned that in order to return to US on 4 July, we must present a "travel certificate" as evidence of negative viral Covid test.

Never even THOUGHT to check US re-entry requirements as i was so focused on ENTRY to Switzerland and France.

Just a heads up for anyone traveling outside US this summer.

Just added $800 ( $200 per person for test ) to trip. Sheeesh.

Edit - make that $1000....must be within 24 hrs of travel and of course, its $50 per more to expedite results.
