With the current travel ban, can a Thai national (and naturalized US citizen) enter Thailand from the US, with ether a Thai or US passport? The reason is because of impending family death. (Sorry if this has been asked before). Thank you.
TLDR : Answer Summary
A Thai national who is also a naturalized US citizen should enter Thailand using their Thai passport to bypass entry restrictions. They will need to provide a Fit to Fly certificate from a doctor and a letter from the Thai Embassy, both issued within 72 hours prior to travel. Entry with a US passport may not be allowed without meeting specific entry requirements for foreigners.
