While it's true that all immigrant children in North America have to deal with a certain amount of conflict between the culture of their parents and the new society they've landed in, some have a harder time of it than others. Obviously those arriving from English-speaking European countries have the easiest time making the transition to the new world. Not only do they have an easier time passing because of skin colour, they usually share a common cultural heritage, or at least one not too far removed from that of their new contemporaries. While they might have some minor adjustments to make, those are nothing to what faces the kids who not only speak different languages, but have a completely different cultural background.
While ethnic heritage can play a major role in determining how easy it is for a child to fit in with his or her new surroundings, those from different religious backgrounds deal with issues that most of us can't even begin to understand. This is especially true for those whose religion teaches a moral and cultural code that is in conflict with what is considered acceptable behaviour in our society. Not only do they find themselves being pulled in two directions at once, being attracted to some aspects of the new but wanting to remain loyal to their traditions, there is also the guilt they feel for any transgressions they see themselves as having committed when they do surrender some of their old moral code.
One of the ways some groups deal with this is by creating insular communities within the overall community at large so as to preserve the integrity of their culture. One of the earliest examples of this were the Jewish immigrants of the late 19th and early 20th centuries who established their own districts in cities in Canada and the US which included places of worship and schools for their children. Gradually over the years the community itself demanded a relaxing of the rules governing their lifestyle and out of that was born the three tiers of Judaism we have today: Reform, Conservative, and Orthodox. This compromise has allowed people to continue to be faithful to their religion while accepting the ways of the world around them to whatever extent they are comfortable with.
