the reason immigrants are often associated with crime is because they normally don't get the opportunity to integrate into their new society, either because they're own cultural differences prevent them to, or they huddle together and alienate the natives, or the natives don't welcome them sufficiently.

I bet most crimes in peaceful arab countries are committed by foreigners also, it's got much less to do with where someone is from rather than where they are

Japan isn't against immigrants, a few are yes but generally immigrants are accepted.
