Do plenty of research first and foremost. Like which country, which city offer best opportunities based on you standing. There are so many online forums you can join and discuss before making the plunge. If you don't plan, you plan to fail. Budget at least six months, i.e. rental, makan, transport, a bit of entertainment, utilities, etc. Do it when you are young not like me when I had family with two children! Less commitment, easier to make decisions and financially less burden too.
