I came to Berlin from India on May 2019 to work as a software engineer in a startup in Berlin.
I received my Blue Card on 30-Sep-2019 and it is valid for 4 years. I also received separate work permit which mentions my present company name.
I was told by the ausländerbehörde that in case of job change I should update them and they will update my work permit with the new company name.
I have a new job offer now. I have mailed the ausländerbehörde more than 2 weeks ago with my blue card details and the new employment contract. I haven't heard from them.
In there website there is no option to book an appointment for 'Change of Employer'. So i am not able to book any appointment. I any case my joining in the new company will be before I can get any appointments.
What should I do ? Can I join the new company with the old work permit and later update it ? Or should the new company try to get the work permit for me?
I am completely lost.
