It’s tough becoming a Swiss citizen. For the third time, Swiss voters have turned down a proposal to make it easier for foreigners to become naturalized Swiss citizens. Nearly 57% of Swiss voters indicated that they don’t want to bring their country’s citizenship requirements in line with other European countries. The vote prevents third-generation foreigners born in Switzerland from becoming citizens. About 20% of the Swiss (1.5 million) population is made up of non-citizens. The French and Italian speaking cantons voted in favor of the changes but the German speaking ones voted against.
