The Index on Citizenship Law in Switzerland measures the relative inclusiveness of legislation on ordinary naturalization and access to electoral rights for foreign nationals across Switzerland’s 26 cantons as of 2017.

In the field of naturalization, the cantons of Zurich, Appenzell Ausserrhoden and Jura have the most inclusive provisions. At the opposite end of the spectrum, the cantons of Aargau, Schwyz and Graubünden have the least inclusive provisions, generally imposing higher requirements in terms of residence, language, civic and cultural integration, good moral character and economic resources.

As for access to electoral rights, only seven cantons have extended the right to vote or stand as a candidate to long-term foreign residents in at least some local elections, while nine cantons allow citizens residing abroad to cast a ballot in cantonal elections from their country of residence.

For a more in-depth analysis of our comparative findings extended to other European, North American and South American countries, read our scientific publications on migrants’ voting rights in national and local elections and on expatriates’ voting rights in regional élections.
