Since 1 January 2019, new conditions for obtaining naturalisation have been in application in Switzerland.
According to Art. 6 of the Swiss Nationality Ordinance, any person wishing to obtain citizenship must demonstrate oral language skills in at least one Swiss national language at reference level B1, and written language skills at least at reference level A2 of the European Reference Framework for Languages.
The Confederation only sets minimum conditions within the framework of the ordinary naturalisation procedure. The cantonal authorities may provide additional conditions for naturalisation and thus require higher levels of language proficiency.
For naturalization, certificates that simply confirm participation in a language course and completed online assessment tests are not enough.
As regards residence and settlement permits, a new law came into effect on 1 January 2019. Federal law requires that candidates for a C licence must provide written proof of level A1 and oral proof of level A2 in one of the national languages. For the B permit, the minimum requirement is level A1 orally.
In these cases, language course certificates or language certificates may be accepted until 31/12/2019.
