Once your visa is approved, you will need to collect your residence permit after you arrive in the Netherlands. This is typically done at the IND (Immigration and Naturalisation Service) desk in Amsterdam (Pieter Calandlaan 1). You will receive an email from Tio with instructions on where to pick up the residence permit and information on how to make an appointment. To make an appointment to pick up your residence permit and more info use this link to the IND website.
