Registering your arrival
As an EU national you will need a residence permit to work in Belgium although you do not need a specific work permit. However it is always best to be prepared, and have employment set up before you go.
You are able to enter the country for up to 3 months as a tourist providing you can prove that you can support yourself financially during this period and have medical insurance, however if you plan to stay longer, you must register with the local town hall (maison communale/gemeentehuis) within eight days of your arrival.
You will need to show a valid passport for the person and all family members, three passport photos each and proof of sufficient means to support yourself and your family. A letter from either your employer or statements from your bank will be required. Some communes may request a legalised birth certificate, legalised proof of your civil status eg marriage, widowed, divorced etc... A copy of a rental lease and some may even take your fingerprints! A nominal tax which varies between 5€ and 20€ depending on your commune, will also need to be paid.
Once all the paperwork is complete, your commune will notify the local police. They will then double check your residence, to ensure you do actually live at the address you provided (ie your name is on the door - so make sure it is!) Providing all checks out, you will then be issued with a temporary residence permit which is valid for a period of 5 months. This will be renewed for one month periods until proof of employment or self employpent and registration with the relevant social security scheme is produced. A permanent identity card, renewable every 5 years, is then issued and the person's name entered on the local population register.
This card must be carried at all times.
