Ra'yii men rai dr. Nasra...
I believe that both marriages can work
If they are willing to but same nationality wont need to worry
About culture and language differences.
For me it's necessary that both of us are from the same country
I guess it's just a nature lol no need to justify!!
The good influence of marrying a foreign wife/husband is unknown for me
lol the bad influence is first of all the language, the kids won't know which language is their nature language, and they will have different values and cultures to follow...
Plus what's wrong with marrying Your Cousin!!!!! And I mean by that "Same nationality"
