Regarding request for "guarantee" letter from US embassy. That I can't return to the US.

Chanthaburi immigration requests a letter from US embassy to say can't return, or should stay abroad.

I'm on 4th covid extension TR60. Arrived late May 2021. Less than a year.

Any advice, as I'm waiting at immigration now. They're waiting for a reply about my ability to get such a letter.

UPDATE: FYI

US embassy website had no information on letters that I could find.

After a little while in immigration, and a few quick questions about why I want to stay, they asked to see my outbound flight documents and hotel receipt.

Next they requested a TM30 from my hotel (my hotel previously said I was registered electronically, hmm), and they asked signed outbound flight docs.

Upon submission, I received a conditional stamp indicating I must return to that office ON April 1st. They explained, I would receive the extension at that time until May 17th ( my flight is 5th, May, so plenty of time). I was considering an ED visa, but doing it in the back of these two stamps is having me think it's better to leave and return on a fresh visa...

I will note, that my previous stamps were in Pattaya, and received:

1 consideration stamp <30 days.

1 extension for 30 days.

Again, I came in on a TR60..

Two of the immigration officers shook their heads when they first saw my

passport.

I can't imagine why.. I'm here for tourism, with appropriate extensions, and with in a year.
