Non-EU foreign nationals (third-country nationals) generally require a residence permit that allows them to work in order to take up employment or participate in vocational training at a company. To this end, a work permit must be issued before they begin working. Residence documents and the residence permit are always issued by the Foreigners’ Registration Office. A work or training permit is granted only if the Federal Employment Agency (BA) has previously approved the specific employment, which involves an assessment of the working conditions. This assessment focuses on ensuring fair compensation and equivalent working conditions for foreign workers.
