May you enjoy your visit to Vienna so much that you wish to stay a little longer and maybe look for a job, you should know that Austria is a member of the European economic area. This means that citizens from the European Union, Norway, and Iceland can work in Vienna without problems. Nationals of third countries, however, may face difficulty getting a work permit because government regulations on the employment of foreigners are quite strict. Get information beforehand.
