You are a muslim and you know that the purpose of marriage is bondage of two families as well and as a muslimah the girl should have NOC from her guardians/wakeels in this case would be parents...without that the marriage might be un valid in technical terms (depends on lots of circumstances, like age etc)

However Qatar on the top of the above has a law which does not allow the local girls to marry expatriates and vice versa (even men are not encouraged for the matter) reasons could be more than one but to manage the population etc....

So the blessed relationship like marriage should bring love and blessing around and not a life starting with problem....

We should all respect the tradional values of the religon and further more the values of the land...in this case either you get a clear concent from her parents and get married again if they can also get you approval of the Govt.

But as all said, you will NOT get the nationality plus you can even lose your job on this..

so be carefull...
