if long as your work is terminated in a legal manner, in this case you are entitled to receive the end of service gratuity and leave wages that you did not get during work and that is in addition to the price of the airfare to return to the place from which you were brought in, 
if the work contract is limitedif the contract is terminated by the worker, then he is liable to compensate the employer for the loss he got as a result of the termination of the contract, provided that the amount of the compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.
in the unlimited contract the worker can terminate the contract after notifying the employer before a month not more than 3 months. If the worker didn’t comply with the notice then he must pay instead of the notice period and the compensation must be as the worker wage for that period full of part of it.
