Asylum systems refer to the legal and procedural frameworks that countries establish to assess and grant protection to individuals who flee their home countries due to persecution or serious threats. These systems play a crucial role in determining who qualifies for asylum based on specific criteria, which typically include fear of persecution based on race, religion, nationality, political opinion, or membership in a particular social group. Asylum systems are vital during migration crises as they influence how countries respond to large numbers of asylum seekers.
