Ok so let me tell you how it works here.
Sy’s had a problem long time ago that people from the community were meeting nice goyish girls and converting them in order to marry them. therefore the rabbis in 1935 made a edict signed by EVERY syrian rabbi that by no means will any convert be allowed to marry a syrian go to out schools or pray in our shuls.
it was resigned in 2010 to strengthen the edict.
It is primarily for asimilation purposes.
