In short
Naturalisation requires 10 years of legal, continuous residence for non-EU nationals, 4 years for EU citizens and 5 years for refugees and stateless persons. You also need Italian at B1, income over the three preceding years, and no disqualifying convictions. The requirement that actually decides cases is none of these: it is the continuity of your municipal registration, because what the administration measures is the register, not the years you remember living here.
The requirement nobody checks first
Citizenship by residence rewards stability, but the way the administration measures stability is purely formal: what counts is registration with the anagrafe, your municipality's population register, and not how long you have actually lived in the country.
Someone who has genuinely been in Italy for twelve years but was struck off the register at some point — a move not reported, a period abroad, a check that found them unreachable at the declared address — can have a qualifying period below the minimum without knowing it. This is the single most common way a sound-looking case fails.
So the first thing to do is not to gather documents. It is to request a historical certificate of residence and reconstruct your own registration history, before paying the €250.00 fee, which is not refunded if the application is refused or withdrawn.
How many years, and for whom
The qualifying period depends on your nationality and status, not on the kind of permit you hold.
- 10 years of legal residence for non-EU nationals.
- 4 years for citizens of another EU member state.
- 5 years for refugees and stateless persons.
- Shorter periods apply in particular situations, including for those born in Italy and for descendants of Italian citizens who do not qualify for recognition by descent.
Income, over three years rather than one
Income is assessed over the three years preceding the application, which is the part people get wrong: a strong current year does not compensate for a weak one two years earlier.
The thresholds are €8,263.31 per year for an applicant with no dependants, €11,362.05 with a dependent spouse, plus €516.00 for each additional dependant.
The practical implication is that timing is a lever. If one of the last three years was below threshold, waiting can be worth more than filing and hoping — and that is a calculation worth doing before the fee, not after.
The language requirement, and a route around it
Italian at B1 is required, certified by a recognised body — CELI, CILS, PLIDA or AIL — or evidenced by a qualification obtained in Italy.
There is a genuine shortcut here, and it is underused. Holders of the EU long-term residence permit are exempt from the language certification for citizenship. Since that permit requires only A2, obtaining it first is often the more efficient path: it removes the need for the higher certification and, with 10 years of validity, also removes the need for permit renewals during the citizenship review.
For anyone whose Italian is somewhere between the two levels, that sequence is worth modelling properly before signing up for a B1 exam.
Criminal record, in Italy and everywhere you have lived
Disqualifying convictions are checked against the Italian record and against the records of the countries where you lived before Italy. The second half of that sentence is where cases stall: those certificates have to be requested abroad, translated and legalised or apostilled, and some countries take months.
Not every conviction is disqualifying, and in some situations rehabilitation changes the position. If there is anything in your history, it should be assessed before the application rather than disclosed and hoped over.
Timescales, honestly
The statutory period is 24 months, extendable to 36 months, for applications filed from 21 December 2020. That is a deadline for the administration, not a delivery date, and in practice the retrieval and legalisation of foreign documents before filing commonly adds several months on top.
After a favourable decision there is one more step that people forget to plan for: the oath before the municipality. Citizenship takes effect from the day after it is taken, not from the date of the decree.
How we work on these cases
We start with the registration history, because it is the requirement that most often decides the outcome and the one applicants are least able to check themselves. Then the three-year income position, then the language route — whether going through the long-term residence permit first is worth it in your case.
That ordering is deliberate: each of those checks can end the enquiry, and all three are cheaper than the document phase that follows. Where a case needs litigation — a refusal to challenge, or administrative silence past the deadline — we put you in touch with the lawyers we work with.
