where are you planning to go to, some countries abroad will accept basically anything, while otheres are fairly strict. In each country it still depends on the institution you are planning to attend, so I would recommend contacting the place you are planning to go to in order to find a more accurate answer. How long have you been teaching for? What is the school system like in Malta, I have never really heard anything about it and it could be pretty interesting. I live in Australia by the way.
