BASEL, SWITZERLAND - FEBRUARY 10:  A Custom Panel announces the border crossing between France, Germany and Switzerland on February 10, 2014 at Basel, Switzerland. Swiss citizens voted with a narrow majority in favour of measures to curb immigration from European Union countries in a move that will require Swiss officials to renegotiate several treaties with the EU. The referendum was launched by the right-wing Swiss People's Party (SVP). Approximately one quarter of people living in Switzerland are foreigners. (Photo by Michele Tantussi/Getty Images)
