🏳️ How do I apply for citizenship, and who helps with the application?

Direct answer

Naturalisation has conditions (years of lawful residence, language level, integration test, income, no serious record), a procedure (application at UK Visas and Immigration (Home Office) (0300 790 6268), 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. HMRC — National Insurance number / General Register Office (0800 141 2079) confirms your registration history, which is the proof of residence years. Civil Legal Advice / Citizens Advice / Law Centres (0345 345 4 345) 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 the UK 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.
