I have moved to the Berlin on February, and Christine was responsible for my visa and registration and the residence permit staff. I can tell you that you will see how it can be fast and qualified at the same time with Christine and her company.
My visa progress has ended almost 2 months before than expected because she was taking care about all the things that should be done.
And also, once I came here, after 3 days, she was already completed my registration.
1 months later, we got the appointment for residence permit from BIS, and the operation was really less than 5 minutes to complete.
Wrapping up, you can directly choose this company for your relocation to Berlin. Don't think twice, nothing else matters !
