"Teaching English conversation really is a bottom-of-the-barrel opportunity. It can be a useful stepping stone but always have some plan for moving on to real work."
I would add to this: If possible avoid English teaching at all cost. If you have a spouse visa you are able to work wherever you like and even for yourself. Lot's of people use the English teaching route to get a visa and then get stuck in a rut of meh pay and meh friends.
