It's not wise for a Muslim to marry a non Muslim in a non Muslim country because they children are more likely to become kufaar. I say this because look at all the Somali kids who have practicing mothers and fathers and yet many of them abandoned the Deen. Imagine marrying a non Muslim man or women that doesn't pray and eats all the yummy gelatin and pig product. Who doesn't wake up for fajr or pray at all. Do you really think that a child wants to wash 5x a day, wake up at 5am everyday and not eat gummy worms? They are going to be like their kafir parent because it's easier and you really can't object because you married a kaafir.
