Hi,
As long as you are still doing the Ausbildung in the Autumn of 2028, then the remark on your Aufenthaltsgestattung should be extended. If you do not complete it by 30.09.28, then they will need to see proof that you are still enrolled on the course.
What I don’t fully understand is why you have a remark on your Aufenthaltsgestattung about the Ausbildung. Are you doing a ‘duale Ausbildung’, i.e. working at a company part of the time and in school the rest of the time? In Germany, physiotherapy is usually offered solely as a school-based ‘schulische Ausbildung’. For a schulische Ausbildung there is no permission needed from the Ausländerbehörde.
Best,
Éanna
