 According to Kymlicka, in contrast to national minorities (and refugees), most immigrants have left their original cultures voluntarily and so are entitled only to a much more limited set of group rights. These “polyethnic rights” are claims to have certain adjustments or accommodations made in the prevailing laws and regulations so as to give individuals access to the social mainstream. Thus, Kymlicka thinks that Orthodox Jews in the U.S. Armed Forces should have the legal right to wear a yarmulke while on duty and Canadian Sikhs have a legitimate claim to be exempt from motorcycle helmet laws (31).
