Dear Salome Mkota,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
First of all, congratulations on the new baby and all the best!
I hope you have read my colleague Alla's answer on your last question? She gave some very important advice here and from my perspective, her recommendations are still valid in your current situation.
If the immigration office is not willing to issue a residence permit according to section 28 of the German Residence Act and insisting you to travel back to Kenya for a visa procedure instead, please contact a lawyer or a migration counselling office for support. Don't worry - the authorities will not seperate you and the child!
Don't hesitate to keep us updated or to get back to us with any further questions as well.
Best wishes,
Meike
