Hi @Mystica28
I presume you have a residence permit based on your Ausbildung. It is possible to change your Ausbildung. Your permit will then be extended in order for you to do this new Ausbildung.
It is important to first secure a new Ausbildung before stopping the first one. Have you looked at the requirements to do an Ausbildung to take care of children? The most common ones I am aware of are ‘Sozialassistentin’ or ‘Erzieherin’. Sozialassistentin is a more basic Ausbildung; you generally require a secondary school certificate at least the level of a German Hauptschulabschluss or Realschulabschluss. For the Erzieherin Ausbildung, you need to first have completed the Sozialassistentin one or, if you have a more advanced school certificate and relevant practical experience, you can be admitted to the course directly. As Germany is a federal country, the specific requirements for these Ausbildung vary depending on which state you are in.
Once you have a contract for the new Ausbildung, you submit it to the Ausländerbehörde. You will also need to show them that you have somewhere to live and that you are able to cover your rent and living costs.
Best,
Éanna
