You do not need a residence permit to study in the Netherlands. However, your enrolment needs to be finalized before the start of the semester (1 September or 1 February). In addition, you may wish to register with the municipality. An appointment with the municipality can be arranged during your Start Appointment.
Once you have been admitted to your study programme, you will be invited to start the UvA immigration procedure. When you follow the link in the invitation email, you will be asked for all the necessary details for your registration, your emergency contact details and a confirmation that you have arranged health insurance. Please note that a health insurance is mandatory in the Netherlands.
