Well, not being funny, but everyones country defines the rules within it's own borders. Ivan is right when he says the inability to adjust to the basic structure of the country you are living in is a problem.
For example many British people retire to France or Spain and never bother to learn the local language, and then we wonder why they get the opinions of us that they do. Same with immigrants etc, I'm not suggesting that they totally abandon their own culture, but, were the situation reversed, they would at least epect us to respect their customs and ways.
Now, before anyone lights up, I'm not saying this is a universal occurence, but certainly in the UK, I have seen occasions of our our customs and ceremonies being altered to suit the strangely delicate dispositions of immigrants, whilst we try to bend over backwards to accomodate as many religious requirements as possible.
