your contract is saying what? What was the period of your contract? They can't simply do it like that, look for another job pare ... go to the labor Department and complain about it and fight for your rights ... you got nothing to lose right? They won't be able to do so [send you back home] if you will go and complain ...

Best Regards ...

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
