Migrants sometimes try to enter or stay in the European Union (EU) without valid documents. This is referred to as irregular migration.
Irregular migrants are individuals who do not possess the valid documents required to enter or remain in an EU Member State. For example, they may lack a valid passport or travel document, or they may use fraudulent documents. EU Member States avoid using the terms illegal migration and illegal migrants, as these imply criminality. The term irregular migration is preferred, as the absence of valid documentation constitutes an administrative infringement rather than a criminal offence.
