Non-EU foreigners (third-country nationals) generally need a residence permit that allows them to be gainfully employed in order to take up employment or undergo in-company vocational training. For this purpose, an employment permit must be issued before they start working. The residence papers and the residence permit are always issued by the Foreigners' Authority. A permit for work or training is only granted if the Federal Employment Agency (BA) approves the specific employment in advance, which involves an examination of the workplace conditions. This is about fair pay and equal working conditions for foreign workers.
