Me and my brothers grew up in the safe Gulf environment in the loving arms of our doting parents..we are Muslim too..and then one by one we all had to go and get those damn degrees lol..big bro went to the US..me the UK..the younger two to different cities in India..by God's grace, not one of us strayed from our religious values/betrayed our parents' trust..sure, we had temptation to deal with often; but you will just have to trust your kids and God to guard them. I was surrounded by alcohol/drugs, had my fair share of female attention and basically could do as I pleased..but at the airport, while my dad just sulked quietly with emotion, my mom hugged me and told me just one thing - 'stay clear of the girls/sex and you'll have done well'..true enough, somehow, even with the UK pub culture and women throwing themselves at you; I came back home chaste as I had left and having never done alcohol/pork/drugs..I'm still single and alone in Qatar now but my parents and religion matter enough to me to be able to resist all the dangers around me.

Send them where they want, trust them, give them your best, the tools to educate themselves and succeed and the rest just trust in Allah. He raised them up safely in the Gulf; he will bring them back much wiser and grown up from the US/Canada inshallah. Best of luck:-)
