Returning to Switzerland involves a number of administrative steps, beginning with reporting your departure to the Swiss representation where you are registered and possibly also to the competent foreign authorities, observing the customs formalities in the host country or reporting your arrival in Switzerland.
Deregistration
You can report your new address to the representation using the Online desk.
Be sure also to initiate in good time the procedures for authorisation of the entry and residence of any family members who are citizens of a foreign country and require formal authorisation prior to entering Swiss territory.
Documents deposited with a Swiss representation abroad
When returning to Switzerland do not forget to reclaim any certificates of origin you have deposited with the Swiss representation at the time of registration. You will need these documents when registering with the municipality of your place of residence in Switzerland.
