The entire process was quick, straightforward, and explained to me very clearly. The team was always friendly, patient, and helpful in answering my questions. Thank you very much for the excellent support! Sincerely, AYŞE DEMİRKAN

After a long and extremely stressful battle with the immigration authorities, the Maibaum Law Firm successfully supported me and finally brought this matter to a positive conclusion.

All the goals we had discussed together were achieved. Ms. Kämpfer, in particular, guided me through the entire process with great competence, dedication, and perseverance. I always felt that my case was taken seriously and that I was represented professionally.

After having fought in vain for a long time for my right to a settlement permit, I was finally able to achieve this goal with the firm’s support. As a result, I now also have the opportunity to apply for German citizenship.

I am very grateful to the firm, and especially to Ms. Kämpfer, for this outstanding work. I can wholeheartedly recommend the firm.

We had an initial consult with Maibaum the first week of December 2025. The second week of January 2026, we decided to move forward with having Maibaum help with our visa application process. Pauline was an excellent support and help in our process! She guided us through the process, provided information and feedback, and was able to submit our visa application 4 weeks from when we started the process. Within 24 hours we had our links to schedule appointments at the consulate. We scheduled the last week of February and the consulate appointment was very easy as they had all our information due to the great work by Pauline and Maibaum! We received our visas 3 days after our appointment! It was because of the great work by Pauline and Maibaum that this went so well. We highly recommend them!

I was facing deportation because my job was deemed unsuitable for my studies—even though I had been doing a very well-paid job for over 15 years. This situation was extremely stressful and frightening for me. The law firm responded immediately to my request and arranged an appointment for me at short notice. From the very first contact, I was welcomed very warmly and taken seriously. Their quick, highly professional, and competent action was a decisive help to me. I would particularly like to thank Mr. Ozan Atas for his great commitment, support, and humanity. Without this help, my situation would have turned out very differently. I am infinitely grateful and can wholeheartedly recommend the law firm.

I had an online legal consultation with lawyer Charlotte Waning about my German immigration plans, specifically the Chancenkarte (Opportunity Card).

She was very professional and clear. She explained the requirements step by step and answered all my questions. She understood my specific situation perfectly and gave me practical advice on what documents I need and how to prepare my application.

I would highly recommend her!
