Brexit & British nationals in Switzerland / Immigration Lawyer

Following the United Kingdom’s exiting the European, the Agreement on the Free Movement of Persons between Switzerland and the EU will no longer apply to British nationals. As a result, British nationals will be treated as third-country nationals (non-EU/EFTA) within the meaning of the Swiss Immigration Act from January 1, 2021. This change will have a significant impact on British nationals who wish to live or work in Switzerland.
The EU has amended the Visa Regulation so that UK citizens can continue to enter the Schengen area and thus Switzerland without a visa for a short stay of max. 90 days (within 180 days). However, for longer stays of more than 90 days, a permit is required, which is subject to the provisions for third-country nationals. In other words, the entry and stay of British nationals in Switzerland is now governed by the same rules as for other third countries.
