[Switzerland]
According to a paper quoted before the Aliens Committee “in some cantons the acts-of naturalization are granted by the legislature, in others by the executive government. In most cantons, among others in Berne, Zurich, Vaud, and Geneva, the privileges are complete and without any restriction from the date of the act. In Tessin a naturalized foreigner can only exercise the rights of citizenship after a lapse of five years from the date of his naturalization. In Thurgovie no one can hold any office in or under the government unless he has been a burgess of the canton at least five years In St. Gall, Thurgovie, and Tessin a foreigner, in order to obtain his naturalization, must renounce his foreign rights of citizenship or allegiance.”
