Berlin has more expats per square kilometre than almost anywhere in Germany — and the Landesamt für Einwanderung, the Finanzamt, and the Krankenkassen know it. They still write to you in German. Every time. Here's what to do when the envelope arrives.

Full guide →🏛️ The Landesamt für Einwanderung — Berlin's immigration authority
Berlin's immigration authority is called the Landesamt für Einwanderung — LEA for short. Unlike most other German cities which use a standard Ausländerbehörde, Berlin has its own state-level immigration office. Same function, different name, considerably longer queues.
The LEA has three locations across the city:
Which location handles your case depends on your permit type and nationality — not your Berlin district. The LEA assigns you to the correct department when you submit your application.
📅 How to get an LEA appointment in 2026
Berlin scrapped its public appointment booking portal in January 2026. The old system was overwhelmed by bots harvesting slots and reselling them for up to €300 on social media. Germany: where you need to schedule an appointment to schedule an appointment — and someone was charging for that privilege.
The current process works like this:
- Submit via the contact form on berlin.de. Upload your documents — passport, current permit, employment contract, proof of address. Maximum 5 PDF files. Write in German. Use DeepL if needed.
- Wait for the LEA to assign you an appointment. They review your documents and email you a slot. If your file is complete, this typically takes a few weeks. If it is incomplete, it sits in a queue with no estimated response time.
- Attend your appointment with all originals. Bring every document listed in your appointment confirmation, plus copies. Unstapled. The LEA keeps the copies.
- Wait for the permit. Processing after the appointment takes five to six weeks. Total timeline from application to permit in hand: commonly three to six months.
Key rule: Apply before your permit expires — not when it expires. If your permit lapses before you apply, you lose the stronger Fiktionswirkung protection. Six to eight weeks before expiry is the LEA's own recommendation. In practice, earlier is better.
🗺️ Berlin vs Brandenburg — the bureaucracy gap
If you live in Königs Wusterhausen, Potsdam, or anywhere else in Brandenburg — even a short commute from Berlin — your immigration experience is noticeably different.
- Contact form only — no self-booking
- Response time: weeks to months
- Total permit timeline: 3–6 months
- Three locations, department-dependent routing
- Bots, backlogs, and the occasional €300 appointment scalper
- Direct appointment booking in most cities
- Wait times typically days to weeks
- Smaller caseloads, faster processing
- One local Ausländerbehörde per Landkreis
- Potsdam slightly busier; smaller towns often same-week
One important note: your Ausländerbehörde is determined by your registered address. Berlin residents must use the LEA — you cannot register in Brandenburg just to use a faster office without actually living there. Some people do attempt this. It tends to create more paperwork than it saves.
💰 Which Finanzamt covers your Berlin address?
Unlike the LEA, which covers all of Berlin centrally, tax matters are handled by district Finanzämter. There are twelve in Berlin, each covering specific postcodes. Your Steuerbescheid, your Steuernummer, and any tax correspondence will come from whichever one covers your registered address.
To find your exact Finanzamt, use the postcode lookup at bzst.de. The Finanzamt processes your Steuererklärung, issues your Steuernummer, and sends your Steuerbescheid. They knew you existed before your neighbours did. The letter with your Steuernummer was probably the first official welcome you got.
📋 The Anmeldung — where everything in Berlin starts
Everything in Berlin flows from one piece of paper: the Anmeldebescheinigung — your address registration confirmation. You must register at a Berlin Bürgeramt within 14 days of moving in. Without it, you cannot open a bank account, get a Steuer-ID, register with a Krankenkasse, or in most cases apply for a residence permit.
Berlin Bürgeramt appointments are in high demand — book one as soon as you have a confirmed address. You can go to any Bürgeramt in Berlin, not only the one closest to you. Some appointment slots are only released by phone (dial 115) or in person. If you cannot get an appointment online, try calling or showing up early on a Monday, Tuesday, or Thursday.
Brandenburg note: You cannot use a Brandenburg Bürgeramt for a Berlin Anmeldung, even if you live just over the border. Your registration must be at the office covering your actual address.
