How Naturalization Actually Works in Berlin: LEA, Online-Only, and the Real Timeline

The Official Rule

Naturalization in Berlin has one authority and one channel, and both changed recently enough that older advice about “going to your district office” is simply wrong now. Since 1 January 2024, the Landesamt für Einwanderung (LEA) has handled every Einbürgerung application for the whole city, a task previously split across Berlin’s district offices. And per Service Berlin’s own Einbürgerung page, the entire process runs online: “Sie können diese Dienstleistung auch online in Anspruch nehmen,” there’s no paper form to mail in and no counter where you can hand over a folder of documents.

The application has two distinct steps, and skipping the first one is the most common avoidable mistake. Before you touch the actual application, Berlin’s Willkommenszentrum instructs applicants to complete the free Quick-Check first, a short, non-binding self-assessment (mainly checking whether your income currently secures your livelihood, the single most common reason applications stall) that takes a few minutes and, per Service Berlin, isn’t saved or transmitted to LEA at all. Only after that do you move to the actual Online-Antrag auf Einbürgerung, which the Willkommenszentrum describes as taking “around 2 hours” to complete, longer than most people expect for an online form, but you can save your progress and come back to it rather than finishing in one sitting.

Eligibility itself is set by federal law, but two of its numbers changed recently enough to trip people up. Under Section 10 of the Staatsangehörigkeitsgesetz (StAG), the standard residence requirement dropped from eight years to five years when Germany’s citizenship law reform took effect on 27 June 2024, and that same reform ended the requirement to give up your existing citizenship, dual and multiple nationality are now generally allowed. A separate 3-year fast track for “besondere Integrationsleistungen” (exceptional integration achievement) existed briefly under the same reform, but the Bundestag repealed it effective 30 October 2025, with no transitional protection for anyone who filed hoping to use it (see our dedicated page on that repeal, it’s federal law, so it applies the same way in every German city). The one 3-year path still standing is different in kind: Section 9 StAG, for spouses and registered partners of German citizens.

The fee is paid by credit card or PayPal at the moment you submit, and it’s due regardless of the outcome. B1-level German is required for the standard path, with exceptions for applicants over 70 or those with documented medical reasons they can’t learn the language, and the Einbürgerungstest (33 questions, 17 correct to pass) remains a separate requirement for most applicants, run at Volkshochschule Berlin exam centers across the city.

How Long It Actually Takes

Ask this question and you’ll get three different answers depending on where you look, and only one of them is official. Service Berlin’s own page is candid about why: it states LEA had roughly 40,000 open cases as of 1 January 2024, the direct result of centralizing every district’s backlog into one office right as application volume was climbing, and warns applicants plainly to expect longer processing times as a result. The city’s own Willkommenszentrum goes one step further and actually commits to a range: “Processing can take one year or longer. Sometimes, however, it may only take a few months,” depending on how complete your documents are and how quickly you respond to any follow-up requests. That’s the single official statement worth planning around.

Everything else online disagrees with it, and with each other:

Read that table for what it actually shows: nobody outside LEA can hand you a confirmed average, and estimates from private businesses selling application help are worth reading with that incentive in mind. What is verifiable is scale: according to the Berlin Senate’s own written answer to the Abgeordnetenhaus (Drucksache 19/26331, June 2026), LEA completed 39,034 naturalizations in 2025, up 79 percent from 21,802 in 2024, and a further 11,905 in the first four months of 2026 alone. The office is genuinely processing more cases than ever, even while individual applicants report wildly different personal timelines.

What Real People Say

The pattern in applicant-facing guides is consistent even where the numbers aren’t: apply online, expect a wait, and don’t count on a fast reply if something goes wrong. Migrando’s practical guide singles out three recurring complaints from applicants: appointments at LEA are “often difficult to get,” delays before a file is even reviewed are common, and “many applicants receive no or delayed responses from the LEA” once they’ve submitted. Their advice matches what other Berlin bureaucracy guides say about LEA generally: use the official contact form for follow-up questions rather than email, since that’s the channel that reliably gets answered.

Technical problems have compounded the wait for some applicants too, not just staffing. LEA’s own online application system had a documented outage between 11 and 12 March, and again between 14 and 16 March 2026, where some applicants who completed payment received an error afterward and their application never actually reached the department responsible for it. Anyone in that position had to notice the missing confirmation themselves and follow up, since nothing about the failed submission was flagged automatically. A narrated walkthrough on YouTube covering the online application step by step reflects the same general advice: screenshot or save a PDF of every confirmation screen as you go, because the process is long enough that you may need to prove later exactly what you submitted and when.

What You’ll Need

• A valid passport and your current residence permit or eAT card, if applicable.
• Proof of five years of continuous lawful residence in Germany (periods where deportation was merely suspended, not periods on a valid residence title, don’t count toward this).
• A B1-level German certificate (telc, Goethe-Institut, or equivalent), unless you qualify for an age or medical exemption.
• Proof you passed the Einbürgerungstest, or documentation showing you’re exempt from it.
• Proof of income that covers your living costs without relying on Bürgergeld or Sozialhilfe, this is exactly what the Quick-Check screens for before you commit to the full application.
• Digital copies (preferably PDF) of every supporting document, ready to upload; incomplete uploads are a common reason files stall in review.
• €255 per adult applicant, €51 per child under 16 applying alongside a parent, payable by card or PayPal at submission.

Step by Step

If Your Timeline Stretches On

A long wait on its own isn’t unusual here, LEA’s own service page admits to a five-figure caseload it inherited in 2024, and even the city’s official guidance won’t promise you a date. But German administrative law doesn’t leave you with nothing to do but wait. Once three full months have passed since your application was genuinely complete and sitting with LEA, with no decision and no valid reason for the delay, you can file an Untätigkeitsklage, a lawsuit for failure to act, at the Verwaltungsgericht Berlin. This has become common enough in Berlin’s naturalization backlog specifically that it has its own dedicated page: see when a lawsuit for inaction actually makes sense for the real cost, the actual court process, and what typically happens once LEA is asked to explain itself to a judge.

Compliance Note

This page explains the general naturalization process at LEA current as of mid-2026. It is not legal advice, and eligibility, document requirements, and processing depend on your specific residence history and case details. For guidance on your own situation, consult LEA directly through its official contact channels or a lawyer specializing in Staatsangehörigkeitsrecht (nationality law).
