Hello! I have been in Germany since 3+ years now with following details:
14.09.22 Aufenthaltserlaubnis 18B Abs.1 AufenthG
And then switched to Blue Card
27.05.24 Blaue Karte EU 18G Abs.1 Satz. 1 AufenthG
The above image is the supplementary sheet (Zusatzblatt).

I will join a new company on 01.02.25. I just wanted to be sure if I should inform the authorities this or it's not required. I'd assume it's not required as per the Zusatzblatt and the recent Blue card regulations. Could someone please confirm? Can I easily switch employers without having to do anything with the German bureaucracy? Any help would be highly appreciated. Thank you!
