My temporary posting to a contracting state outside the EU/EFTA will be longer than the duration provided for in the agreement. Can I retain my Swiss social security cover?

Should the posting period be insufficient, your employer can apply for a posting extension on the ALPS web application (access provided by their OASI office). The extension may not exceed the maximum posting period of five/six years. The Federal Social Insurance Office (FSIO) will try to reach a special agreement with the competent authority in the country of temporary employment.

If an agreement is reached, the employer will receive confirmation that you remain covered by the Swiss social security system.
