I am planning on going on a 10 month trip after my study as a Dutch citizen. In this 10 months I mostly want to travel, but as money will be needed at some point, I also want to work. By that time I will be 24 years old and have a master's degree, but as big companies probably won't hire me for 2-3 months I am aiming at more simple jobs like being a waiter, a postman, or something along those lines.
From this question I understand that my plan will not be executable in the USA as I'm not allowed to work on a nonimmigrant visa.
What non third world countries do allow temporary employment of foreigners in a way that will make my plan feasible?
