In the future, you might consider signing up for a Medicare Advantage plan. Some of these cover you for at least 60 days abroad. But you should check your certificate of coverage to make sure.

I'm over 50 and plan to stay in Thailand indefinitely,

Thank you. That should keep me here till I return to US and apply for the new visa.

I am living here. I will renew my Non Immigrant OA visa when I go to the US in April, but just want to make sure I can stay for 30-day periods until then by doing visa runs as needed.

Wonderful,

@Benjamin *****

. Perfect answer. Thank you very much.

Two weeks ago returned from Cambodia and brought my US health insurance contract just in case....but nothing was mentioned and I'm stamped in just fine.

@Paul ********

the passport is valid until 2024.

@Benjamin *****

thanks for the correction.

@Al ******

, the visa sticker shows VALID FROM 24 Jan 2018 and VALID UNTIL 23 Jan 2019.

Thank you Al, yes, this is a Non-immigrant O-A multiple entry visa obtained from the Thai consulate in the US. When I returned from a trip to Vietnam on Jan. 12, my passport was stamped until June 11 for reasons I cannot quite figure out. And given that, is it possible for me to travel outside Thailand between now and June, and would still have validity to stay until June 11 rather than a standard 30-day stay?
