A Qatari doesn't need prior permission to marry a GCC citizen "unless ur in the Army/Police"...u do however need a permit to marry anyone from outside the GCC....for several reasons of course "not that I agree with them at all" but preserving the culture, controlling gold diggers, and reducing numbers of unwedded Qatari females.

How do I know???

I did it myself & I married a GCC Citizen :DDDD

Plus My brother and Uncle both married from non-Qatari/non-GCC citizens.

No prior permission is needed if ur marrying from the GCC....once the wedding papers are signed u need to get them stamped at the Qatari Consulate or Embassy in ur wife's country, then get it certified in court in Qatar and FINISHED ur done...quite painless and very straight forward...TOOK ME A DAY ONLY in her country and likewise in Qatar....Both times I was done by 8:30am!!!
