Thurgau Einbürgerungstest — Einbürgerung Kanton Thurgau (Swiss Citizenship Knowledge Test)

Ordinary naturalisation in the canton of Thurgau has three stages: the municipal citizenship (Gemeindebürgerrecht), the federal naturalisation permit from the State Secretariat for Migration, and the cantonal citizenship, which the Grosser Rat grants. Applicants need a C permit, usually 10 years of residence in Switzerland, 5 of them in Thurgau and the last 3 without a break in the municipality, and German at oral B2 and written B1. Knowledge of local, cantonal and Swiss living conditions is shown by a test or in an interview if it is not evident (KBüG TG § 6 Abs. 2); the municipality carries out these checks; we found no common cantonal test or question catalogue on the canton’s pages. The ordinance lists basic knowledge of the geographical, historical, political and social conditions in the municipality, the canton and Switzerland (KBüV TG § 5). Cantonal fee CHF 800 for an adult; federal fee CHF 100 for a single adult (CHF 150 for a married couple applying together); municipal fees vary (hz.tg.ch, read 9 Nov 2026).
