Switzerland's asylum residence permits are varied and grant very different rights. Any foreigner staying in Switzerland for more than three months must have a residence permit. On arrival in Switzerland, an asylum procedure can be opened by a simple request at an airport or border crossing. Since March 1, 2019, asylum procedures have been carried out in six areas of the country. A Federal Center for Asylum Seekers (CFA), responsible for procedural tasks, is located in each of them.
