Reintroduction of restrictions for Romanian and Bulgarian Nationals
Since June 1, 2016 citizens from Romania and Bulgaria benefited from the full free movement rights laid down in the Agreement on the Free Movement of Persons between Switzerland and the EU (AFMP). I.e. as from that date Romanian and Bulgarian citizens, who fulfill the qualifications to be granted a right of residence, could take up residence and start working in Switzerland without previously being subject to labor market access examinations. On May 10, 2017 the Swiss Federal Council made use of its right to unilaterally invoke the safeguard clause. This was possible due to the fact that within a year's time the threshold of workers immigrating from Romania and Bulgaria as set in the AFMP was exceeded. Concretely, this means that as from June 1, 2017 onwards Romanian and Bulgarian citizens desiring to take up work for more than 12 months or for an indefinite period of time can only work in Switzerland with restrictions based on quotas. B-Permits for nationals of the two countries are restricted to a quota of 996, which will evenly be allocated throughout the next year (i.e. June 1, 2017 to May 31, 2018) and thus proportionally released on a quarterly basis. Not affected by the restrictions are short time residence and work permits (permit type L).
What this means for your recruiting cases
Recruiting Romanian and Bulgarian nationals has to be re-planned. You might want to assess whether anticipating the filing of an application for a B-permit still in May 2017 is feasible (unlimited access). If not, the application is to be filed at the beginning of the respective quarter (first come, first serve) or it is to be considered whether applying for an L permit would suffice.
