An asylum application is a request by a non-Swiss citizen to be admitted to Switzerland and protected from persecution. The application is not subject to any formal requirements; it may be submitted orally or in writing at any Swiss border guard post or during customs clearing at an airport on arrival in Switzerland. Persons seeking asylum need to prove their identity to the Swiss authorities, possibly by means of an official document. Applicants are further required state the reason or reasons causing them to leave their home countries. It is in the interest of those seeking asylum to provide appropriate documentary evidence in proof of their statements.
Most asylum applications are filed directly at one of the asylum seekers reception centres, operated by the Federal Office for Migration.
