How difficult it is to get a TT in the U.S. after leaving the country? I completed my higher ed in the U.S. (from B.A. to Ph.D.) and have been in this country for 12 years. I received a TT offer from a teaching university ( I didn't enjoy it but appreciated the opportunity), but the visa thing didn't work out. At this point, I'll have to leave the country because I'm at the end of my OPT.
I received a job offer from my home country. The university itself is an English-teaching institute with a decent teaching load, and they are pushing for research. As far as I know, my future colleagues are most foreigners  (Korean, American, German, etc.). The pay is decent as well.
Therefore, I have two questions:

is it still possible for me to get a TT position in the U.S. after leaving?
will my work experience outside the U.S. be counted/valued?

I have been interviewing at different universities, but my choices of the school were more out of desperation than what I wanted. The school that I loved most had to pause their search due to COVID, and I missed more than half of the applications because the former employer didn't inform me about the situation until March. After many hard and tearing days, I am wondering if I should take the job offer back home to continue doing what I do with much better support to do research. But I fear that I won't be back in the states after leaving here.
I'd be glad to know your experience or suggestions! Thank you in advance!
Q1. Is it possible to get a TT position in the US after leaving?
Yes, it is possible; I have done something similar (in Computer Science). I left the US to do an extended PostDoc and then returned to the US as a professor. This worked out for me in particular because I had experience and expertise in a specific area that the school was looking for. (And &gt;40 publications by the time I returned.)
Q2. Will my work experience outside the US be counted/valued?
If you are productive there typically is no reason it won't. In particular, you need to continue to publish high quality work at top venues. This may be harder to do if you don't have good students. In this case you may look for good collaborators and do things like invite their students for research visits.
