Assembly And Project Assignments Abroad Part 2: Project And Assembly Assignments Abroad: When Is A Work Permit Required?

A work permit is required for most project and assembly assignments. There are only a few exceptions to this rule. The decisive factors for assessing whether and what type of permit is required are

• The nationality of the person
• If the person is an employee or self-employed
• The employer's country of domicile or place of registration of the self-employed activity
• The location
• The duration of the project or assembly assignment
• The type of activity

Based on this information, it is possible to determine which legal regulations apply. This information is also decisive for determining social insurance coverage and tax liability.

Switzerland

In Switzerland, we generally use either the notification procedure or the 120-day permit for short-term project and assembly assignments. Only for assignments lasting longer than 4 months at a time do we apply for a short-term residence permit for the corresponding duration of the assignment.
