The agreement allows UK companies that send workers to Switzerland (and self-employed workers established in the UK and of British nationality) to continue to use the declaration procedure for travel of up to 90 days per calendar year and are not subject to a prior labour market assessment, despite Brexit. Details of the agreement have yet to be published, but it will contain provisions on the recognition of professional qualifications. On 4 December 2020, the Federal Council also approved an agreement between Switzerland and the United Kingdom on the reciprocal provision of services, which facilitates and authorises UK service providers to use the notification procedure for up to 90 days to work in Switzerland. This provision is limited to two years, but may be extended by mutual agreement between the parties.
