While neutral Switzerland is not a member of the EU,
its immigration policy is based on free movement of citizens to and from
the EU, with some exceptions, as well as allowing in a restricted
number of non-EU citizens.
That pact on free movement of
people, which came into force 12 years ago, was signed as part of a
package of agreements with the EU, some of which could now be in danger
of unravelling, to say nothing of the effect on a globally oriented
economy that employs large numbers of foreign professionals.
