i'm doing some research about teaching english in brazil. i want to know what the current rates of pay are, and how much the average rents are in both the cities and country areas. is it easy to rent an apartment, and where is the best place to look? how long does it take to get a visa. i've heard lots of esl teachers go on tourist or student visas. does anyone have any experience of this? also, what are some general prices for food, drinks, movie tickets etc? thanks in advance!
