From 15 June 2020, border controls between Switzerland and the other Schengen states will be lifted and normal entry requirements will apply again with the Schengen states only.
Since 18 March 2020 Switzerland no longer issues Schengen visas. National visas are only issued in exceptional cases (family members of Swiss citizens or residents, etc.).
The current visa suspension for third-country nationals remains in force and at the moment it is not possible to apply for a visa. Switzerland follows the practice of the other Schengen states.
