ZURICH, Switzerland, Feb. 8 (UPI) -- Political observers in Switzerland predicted passage of a controversial cap on immigration in Sunday's referendum.
Swiss voters go to the polls for what was expected to be a close vote on the measure, which would limit the number of foreign workers entering the country each year.
Euronews said final polls showed growing support for the restrictions, although opponents held the majority heading into the election.
Switzerland's healthy economy has been a draw to immigrants in recent years, which has many Swiss unhappy with larger crowds, particularly on the roads and railways.
Opponents of the cap argue Switzerland needs more skilled workers from the European Union and other nations for the economy to thrive over the long-haul.
The BBC said passage of the measure would require Switzerland to renegotiate various deals with the EU, including the Schengen Treaty that allows relatively free movement of workers around Europe. Switzerland is not part of the EU but has adopted a number of its policies, including the Schengen pact.
