Peace be upon you
the answer depends on what are those white blacks do there?
study or married?
there are married there but hardly I met one who stay all the year with his ,her partner there... just holidays..
study :yes lots of blacks ,Asians ,Turkish I met there and some Europeans and Americans too.... study in Alazhar university ...
most people there understand English in varied degrees....... and the cost of living is almost nothing for foreigners ...
anytime you decide to go just tell me and my family,my flat ,my friends all will be at your service till you systemize your life and decide whether you continue there or not..
peace
