forget applying/considering citizenship for different countries. Being an expat is the best thing i have done (almost 10 years for me now). I am currently in the Middle East now and there are lots of opportunities for teachers (especially with specialism like autism). Remember that you will still have to file IRS as your income is still taxable outside the US – there are ways around that too ;)
You may have to get a TEFL course (easy to do :) )
I would recommend you to look at Middle East or Asia (Thailand, Japan, Singapore).
