How to deal with an employer if they are not ready...

We would like to inform you that according to the Qatari Labor Law and for the purposes of leave and return to your country, you must terminate the work according to the legal rules.
Article (49):
If the service contract is of an indefinite duration any of the two parties thereto may terminate it without giving the reasons for the termination. In this case the party intending to terminate the contract shall notify the other party in writing as follows:-
1. In respect of the workers who receive their wages annually or monthly, the notification shall be given not less than one month prior to the date of the termination if the period of service is five years or less. If the period of service is more than five years, the notification period shall be at least two months prior to the date of termination.
2. In all other cases the notification shall be given in accordance with the following periods:
A) If the period of service is less than one year the notification period shall be at least one week.
B) If the period of service is more than one year and less than five years the notification period shall be at least two weeks.
C) If the service period is more than five years the notification period shall be at least one month. If the contract is terminated without observing these periods, the party terminating the contract shall be obligated to compensate the other party for an amount equivalent to the wage for the notice period or the remaining part thereof.
As for leave and booking of the airline ticket, the employer is obliged to do so if she is the one who decided to finish the work.
