I've helped hundreds of expats survive their first 90 days in Germany. Here are 5 words that Duolingo will never teach you — but that you absolutely need before walking into the Ausländerbehörde:

1. Aufenthaltstitel (Residence Permit)

This is what you're there to get. If you don't know this word, you won't understand a single question they ask you. It's on every form, every letter, every status update.

2. Meldebescheinigung (Registration Certificate)

You need this BEFORE your visa appointment. It's the paper you get from the Bürgeramt proving you registered your address. No Meldebescheinigung = no Aufenthaltstitel. Period.

3. Krankenversicherung (Health Insurance)

They will ask for proof. The word itself is 21 letters long and they'll say it fast. Know it. Have the document ready.

4. Erwerbstätigkeit (Employment/Gainful Activity)

This appears on your visa conditions. It determines whether you're allowed to work, and how many hours. Misunderstanding this word has cost people their jobs.

5. Frist (Deadline)

The shortest word on this list and the most dangerous to miss. When you see "Frist" on a letter, you have a limited time to respond. Miss it and you start the process over — or worse.

These aren't textbook words. They're survival words.

I built The Expat Survival German Guide specifically for people who need to navigate German bureaucracy at an A1/A2 level — not order food or describe the weather.

200 critical terms. Anki flashcards. Grammar shortcuts. Cheat sheets for the Bürgeramt and Ausländerbehörde.

If you're moving to Germany, this is where you start.
