Consult the FDFA’s comprehensive country information for Swiss citizens who are thinking about emigrating, as well as its travel advice bulletins and pages on specific countries.
You can also obtain information from the official Swiss representation (embassy or consulate) in the country of destination. So if you are unable to obtain the necessary information in Switzerland, contact the representation in the country concerned, which will be pleased to make the desired enquiries upon payment of the associated costs.
Visit your future country of residence several times for at least two to three months and at different times of year before deciding to emigrate there. It is easier to obtain information when you are in the country concerned, and you can also gain valuable impressions of what it would be like to live there.
