If you've lived in the Netherlands for an extended period, typically a few years, you may have the opportunity to obtain Dutch nationality. The Gemeente Groningen (Municipality of Groningen) website provides more information on how to apply for this.
Passport and Identity Card
Everyone in the Netherlands is required to carry identification. For this purpose, you would need a passport or an identity card. A passport allows you to travel worldwide. An identity card is cheaper but comes with certain limitations compared to a passport. Apart from these two types of identification documents, there are other ways to prove your identity based on your situation. The Gemeente Groningen website has more information on this.
Registration with the Municipality
Once you've arrived in the Netherlands, there are several things you need to take care of. The first thing to do is to register with the municipality where you'll be living. IWCN has a page where you can find more information about municipal registration. This registration is essential because you'll need a Citizen Service Number (BSN) to study or work in the Netherlands. You also need a BSN for healthcare, insurance, and opening a bank account. If you're having trouble with this process, IWCN might be able to assist you.
