I often visit Bosnia on business trips. From what I've heard, there are more and more cases of foreign settlers disturbing locals for drinking alcohol or dressing inappropriately. There is a vast difference in mentality between Bosnians and Saudis, but I guess you already know that. In any case, I believe it is a big mistake to allow those people to be settled in any European country. In Bosnia, they purchase land in the suburbs of cities and build quarters of buildings or houses, separating themselves from the start. Not a good sign for the future.
