The European Migration Network has published an Inform on preventing, detecting and tackling situations where authorisations to reside in the EU for the purpose of study are misused. The Inform outlines approaches, experiences and best practices in monitoring, detecting and dealing with cases of abuse, from minor breaches of immigration conditions to fraudulent applications. The inform also addresses the grey area between deliberate abuse and unintentional mistakes, and the difficulties the authorities may have to distinguish between the two.
The Inform can be found by following this link.
