One of the issues you may encounter is that many schools prefer you to be from Australia, UK or USA. Also I think some schools can be a little discriminating in that their ideal teacher has blond hair and blue eyes.
It's not one of the issues you may encounter, they are actually the main requirements. If you meet these requirements you won't even need to worry about any certificates or teaching experience. They don't really count here. You will be picked up at the airport and taken directly to your apartment, from where you will go to work the next morning and be probably made the head of department straight away. Get a white mask brother if you can afford one! If you can't, get a few big gold looking chains, some NBA shirts, high-heel sneakers and practise talking a lot about the NBA, rap and hip hop singers. A job will be waiting for you at the school nearest to the airport you will arrive at.
Peace!
