Dear @Hakeem,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
I am not totally sure what kind of details you need - but my colleague was providing some information on a similar question here before.
Regarding residence law, for example if you want to apply for a permanent residence permit (Niederlassungserlaubnis), it will be important that you haven't committed any major offences (minor convictions with fines of up to 90 days of income or suspended sentences of up to three months do not affect your case). For the so-called "Chancen-Aufenthaltsrecht" (residende permit according to 104c of the German Residence Act), you must not have committed an intentional criminal offence above certain limits (prison sentences or fines equaling 51 daily rates or more or criminal offences punishable by 91 daily rates or more for criminal offences under the Residence or Asylum Act) either.
I hope this helps and please don't hesitate to get back to if I misunderstood your issue of if you have any further questions.
All the best,
Meike
