I went to the comune to register myself since I am portuguese and I was informed that the police would stop by my house to confirm the address.
I was not home when they came so I had to go to the police station. After the police confirmed that I was really living in belgium, I had to go to the police station to pick up a copy of the confirmation.
Can anyone tell me wich is the next procedure? I have the copy of the confirmation but I don't know what to do with it.
