Dear @Dickson,
Welcome back to the Wefugees Community and thank you for your question.
Some of the requirements for the residence permit according to section 25b of the German Residence Act were changed at the beginning of 2023 - i.e. the time the applicant has to have stayed legally in Germany (6 years or 4 years with minor children). Please see a list with the conditions here.
In case you live in a single-person household, you may be eligible for the 25b in less than a year!?
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
