Although researchers in most cases are exempt from
standard work permit procedures, some routine
regulations may still apply
Researchers with the nationality of
EU/EEA-countries and Switzerland may carry out
their scientific research activities which are not subject
to the regulations of the Austrian Act Governing
Employment of Foreign Nationals (Ausländerbeschäftigungsgesetz)
without any further permit. However nationals of Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia however, still need a work permit for any gainful employment that goes beyond these scientific research activities.
Researchers from third countries who are in possession of a residence permit "special cases of gainful employment" (Aufenthaltsbewilligung Sonderfälle unselbständiger Erwerbstätiger) or a residence permit "researcher" (Aufenthaltsbewilligung Forscher) (both for scientific research activities which are not subject to the regulations of the Austrian Act Governing Employment of Foreign Nationals) may carry out their scientific research activities without any further permit. However they may not take up any additional employment.
The Public Employment Service (Arbeitsmarktservice AMS) is the competent authority for work permits.
