Recently removed from the open list
The following countries had been allowing US citizens to enter but have closed again or were removed by CNN Travel for other reasons:
— Bangladesh: While technically still open, a flight suspension and lockdown until at least midnight May 5 makes travel there highly difficult.
— Cambodia: The US Embassy reports the Southeast Asian nation has stopped issuing tourist visas; you can still apply for business-linked visas.
— Chile: It has closed its borders to almost all tourists through May.
— Saba: The very extensive entry requirements currently exclude all but a few US citizens from this small Caribbean island.
— St. Barts: Temporarily closed to all tourists.
