Decent CFI job? ain't no such thing...you will be on the poor side of life ...I do think you would be better off for flying in a richer part of the USA.
more than 30 years ago I instructed in silicon valley (KPAO). I was poor but got over 1500 hours dual given.
in 1975 learned to fly when you could rent a piper cherokee for 12 US dollars an hour including gasoline.
its more than 10 times that now. the minimum wage has gone up 5 times (500percent) but flying has gone up 1000percent.
so, go where the people are rich and the weather is good. of course you won't be able to really live in great style.
now, you can give it a try and I hope you are a good pilot and cfi...but no guarantees
and quite frankly, if I had to hire someone, I would hire a US citizen.
