I have a German Blue Card and want to change my employer. According to the rule for Blue Card holders:
For the first two years of employment, approval from the Foreigners’ Registration Office must be obtained before any change of job.
My current job contract started on 01.04.2018. Am I allowed to change my employer from 01.04.2020 without approval? Can I just sign a contract that starts on 01.04.2020? I have a Blue Card visa in my passport and also as a card with different dates; are they linked?
I cannot ask the authorities as they are closed.
