I would say that teaching overseas will be a great experience, maybe even one of the best things that your career can offer. I have taught in two schools overseas and am currently in Doha. I suggest that you think carefully about your choice of place and choice of school. There are lots of bad schools out there, but you can research and be wise about it. Doha is a bit of a crazy place....I wonder if it would be your ideal place in terms of teaching and lifestyle. Please PM me if you have any questions about the place.
