How do I apply for citizenship, and who helps with the application?
Naturalisation has conditions (years of lawful residence, language level, integration test, income, no serious record), a procedure (application at Dienst Vreemdelingenzaken / gemeente — dienst vreemdelingen (02 488 80 00), fee, interview, a decision within a legal deadline that is often exceeded), and consequences you should check first — whether you may keep your current nationality. Dienst Bevolking van de gemeente / Mijn Burgerprofiel (belgium.be) confirms your registration history, which is the proof of residence years. Bureau voor Juridische Bijstand (pro Deo) / Justitiehuis (advocaat.be) advises for free if the case is complicated (gaps, a refusal, a criminal record).

❓ Frequently asked
Do my children get citizenship too?
Usually included in the parent's application if minors and living with you; ask to add them explicitly.
I was abroad for a year in between
Long absences can break the residence count; check the rule for Belgium before you apply, and explain the reason if allowed.
How long does it take?
From several months to a couple of years. The legal deadline gives you a lever (notice of default) if it is exceeded.
