You can apply for a DigiD online from abroad. You will receive a counter code that you take with you to your appointment at the DigiD abroad counter in Heerlen.
Have you been living in the Netherlands for less than 4 months? You can register in the Non-Residents Registration System (RNI). You will receive a BSN after registering.
You will need a residence permit if you wish to stay in the Netherlands for longer than 90 days. Apply for this at the Immigration and Naturalization Service (IND).
