The abandonment of the Confederation by its citizens is assuming the contours of a structural phenomenon. According to data processed by the Federal Statistical Office (FSO), the number of Swiss who chose to settle just across the border reached 154,700.

Key points

Anyone who decides to take this path must consider various bureaucratic and fiscal aspects. Although one becomes a resident abroad, the link to Switzerland often remains strong through work.
