hi
first u take permission from parents, then they submit ur papers in marriage authority (lajna zawaj) then they give u a date. they take ur interview and ur g/f interview about (y she want 2 marry with u , y she was nt choosing in their nationality ) i hope u understand what i mean ( bcoz she is educated and she can marry any qatari guy) then if they say ok then they give u permission then u have 2 go ministry of interior and take a permission from there. (its nt a big deal) if u get a approval from marriage authority then they didnt ask u any thing .they give u a permission on same day they u can marry her in doha. bcoz i am also in the same problem like u . best of luck
