Passport and Belgian Visa
All nationals except EU nationals holding a valid national ID card require passport valid for at least three months beyond length of stay. Some EU nationals may be required to present a valid passport in addition to a national ID card.
EU nationals with valid passports are free to come and go, but they must register at the local police station or town hall within eight days of arrival. Children must also be registered. The period of their stay (more or less than three months) in Belgium and their capacity (employee, student, family member) will determine if a residence permit needs to be issued.
Since March 1995, the Schengen Agreement regulates Belgium's visa application process. Schengen visas, regardless of which member country issues them, are valid in all member countries for a short-term stay, not exceeding 90 days.
Possession of Belgian visa does not guarantee entry to Belgium
The final decision is made on a point of entry to Belgium on conditions that "The traveler can justify the purpose and conditions of the intended stay, and has sufficient means of subsistence, both for the duration of the intended stay and for the return to his or her country of origin or transit to a third country into which the traveler is certain to be admitted, or is in a position to acquire such means lawfully" and other security conditions. "The requirements of a visa for short-term stays ... do not involve employment or any self-employed activity". Finally, "the traveler must have travel insurance that covers, for a minimum of €30,000, any expenses incurred as a result of emergency medical treatment or repatriation for health reasons".
