Well my other pet peeve re:immigrants, is STOP marinating in perfume (aftershave, cologne, whatever), we have cheap soap and water here people. Simply bathing is usually enough with a dab of deodorant. I do have to say that from working in aerospace/defense and biomed that the typical Russian (any ex-Soviet european type anyway), Indian, West African and Oriental does a reasonable job of assimilating while still managing to retain some of their culture. Note that these are usually the better educated people from those regions.
