Pls do not compare with the salary of QP - which is a Govt owned Petroleum cmpany. Among the private sector, this is a GOOD salary. TEYSEER is a respected group, the top Management is controlled by some of the professional Indians.

I would advise 2 things for the negotiation.

1. Ask for the chidlren education allowance. or tell them to reimburse the amount, whatever actuals.

2. Ask them, why dont them provide you a Resident visa instead of business visa. Being a reputed comapny they dont have scarcity of Indian visas. Anyway, plese reach here alone not with family - pls bring them only after you get resident visa.
( if something unfortunate happens, pls take it as a paid holiday trip to India-Qatar-India.... right > )
