How Long Does It Take to Become a Citizen? By Country

Ask how long naturalization takes and you will usually be told a single number: five years, ten years, three. That number is the residence requirement, and it is only the first of three stages. The full answer is residence, plus preparation, plus processing, and the last one is where people are surprised. Here is the realistic picture for eight countries, and which parts you can influence.

The three stages

1. Residence. The years you must hold lawful residence before you may apply. Fixed by law and impossible to shorten.
2. Preparation. Language certificate, civics test, document gathering, translations and legalisation. Typically three to twelve months, and almost entirely under your control.
3. Processing. From filing to decision, then the ceremony or oath. Months to years, depending on country and caseload.

United States

Five years as a lawful permanent resident, or three if married to and living with a US citizen. Filing Form N-400 is followed by biometrics, the interview with the civics and English tests, then the oath ceremony. The civics test version depends on your filing date, which matters more than most applicants realise: see 2008 vs 2025 explained. Full route in how to become a US citizen.

Canada

Three years of physical presence within the five years before applying, counted in days, so travel matters. The knowledge test and language requirement apply to ages 18 to 54. After approval comes the citizenship ceremony and the oath. Details in how to become a Canadian citizen.

United Kingdom

Usually five years of lawful residence plus twelve months holding indefinite leave to remain, so six years in total, or three years if married to a British citizen with settled status. You need the Life in the UK test and evidence of English before applying. The test is a fixed cost and a fixed format: the Life in the UK test.

Germany

Five years of lawful residence under the reformed law, with a shorter path for applicants who demonstrate exceptional integration. You need B1 German, the Einbürgerungstest and proof that you can support yourself. Dual citizenship is generally permitted since 2024. See how to become a German citizen.

France

Five years of habitual residence as a general rule, reduced in specific cases such as graduates of French higher education. Since 2026 the path includes a B2 language requirement and a formal civic exam alongside the prefecture interview. The interview is scheduled by the prefecture, and that scheduling is often the longest single wait. Preparation: the naturalisation interview.

Spain

Ten years as a general rule, five for refugees, two for nationals of Latin American countries, Andorra, the Philippines, Equatorial Guinea, Portugal and for Sephardic Jews, and one year in several specific cases including being born in Spain or married to a Spanish national for at least a year. You need the CCSE and, unless exempt, the DELE A2. The legal decision deadline is one year from a complete file, and in practice it often runs longer. Steps in nacionalidad española por residencia.

Sweden

Five years of residence for most applicants, with shorter periods for some groups. Since 15 August 2026 the civic knowledge test, Medborgarskapsprovet, applies to standard adult applicants. Migrationsverket publishes current processing estimates, which have historically been long. See how to get Swedish citizenship.

Denmark

Nine years of residence in the general case, plus Danish language at the required level, the Indfødsretsprøven and a set of conditions on self support and criminal record. Danish citizenship is then granted by an act of parliament, which is passed twice a year, so the final stage has fixed dates rather than a rolling queue. Guide: the Indfødsretsprøven.

Where the time actually goes

• Foreign documents are the slowest item. A birth certificate that needs an apostille and a sworn translation can take months to obtain from abroad. Start these before anything else.
• Criminal record certificates expire. Requesting one too early is as damaging as too late, because it may lapse before your file is reviewed. Sequence them deliberately.
• Requests for more information stop the clock. Answering within days rather than weeks is the single biggest lever you have on total duration.
• Test failures cost a fixed block of time. In Denmark a failed test means waiting roughly six months for the next sitting. Preparing properly the first time is worth more than it looks.
• Ceremonies are scheduled, not instant. Approval is not the last step in most countries. Budget for the oath or ceremony date.

You cannot shorten the residence years. You can remove every avoidable month after them, and those add up to more than most applicants expect.

A sensible order of operations

1. Twelve months out: confirm your residence count and gather foreign documents with apostille and translation.
2. Six months out: book and pass the language certificate if you need one, since these have the fewest sittings.
3. Three months out: prepare and sit the civics test. The 30 day study plan is enough for most countries.
4. One month out: assemble the file, check every expiry date, then submit.
5. After filing: answer every official request immediately and keep copies of everything you send.

For expectations on the study stage specifically, see how long it takes to prepare, and for the exemptions that remove the test entirely, who is exempt. Rules and processing times change, so treat the official authority in your country as the final word.

FAQ

Which country has the shortest residence requirement?

Among the eight covered here, Canada and Germany are the quickest common routes at three and five years respectively, with Germany allowing a shorter path for exceptional integration. France and Spain require five and ten years as a general rule, with Spain dropping to two years for nationals of Latin American countries, Andorra, the Philippines, Equatorial Guinea and Portugal.

Does time as a student count towards naturalization?

It depends on the country and the permit. Several countries count only time held with a residence permit rather than a study or visitor status, or count study years at a reduced rate. Check how your specific years are classified before assuming they count.

What delays a citizenship application the most?

Incomplete documents. Missing an apostille, submitting a criminal record certificate that has expired, or failing to respond to a request for more information typically costs more months than any processing queue.

Can I speed up the process?

You cannot shorten the residence requirement, but you can control preparation. Passing the language and civics tests early, gathering foreign documents before you need them and answering official requests immediately remove the delays that are actually yours.
