Great information, Psyguy. Thank you very much for the response. I am going to pursue the MA License. I will report back if (when?) I ever get it.

Many thanks for the reply - I am in Asia, but unfortunately not in any of the cities they have listed. I have considered programs like TeachNow or TeacherReady, but like this program they're prohibitively expensive given my salary.

Apologies for probably beating this issue to death. I've searched and read quite a bit but I'm drowning in a sea of information.

1) BA in non-Ed related field, MA TESOL with ESOL endorsement
2) 2 years experience in cram schools, 4 in public/private schools
3) US citizen with no plans to return

What I've been able to glean so far is the following:

1) UT - initial is good for 3 years, but one-shot with no way to renew.
2) MA - provisional is effectively forever since I won't be in MA. Is this my best option?
3) CT - initial also sounds like a valid option, with up to 18 years availability. Would this also be possible?

Would appreciate advice on what the best path for me is, or maybe something else I have not considered yet. Many thanks!
