thats not true Imz
have a christian friend who married a muslim guy here in doha just a couple of months ago
there was no trouble at all
the judge dude at the court just asked him though why not a muslim girl and he told him "the heart wants what it wants" and he blessed the wedding.
u just need to go down to the sharia court i think and its done. You will prob have to transfer ur sponsorship to ur husband's name then tho.
