Hi @Coop
I have just answered another question on the new law here:
https://***.wefugees.de/816065/asyl-spurwechsel
From what I have read, the new law will not for now have an impact on you as you are still doing an Ausbildung. Once you have completed the Ausbildung, it will then apply to you as a qualification and you can apply for it.
I do not follow your remark about 25b after 4 years. It is possible to get paragraph 25b after 4 years if the person has a child. In other cases it is only possible after 6 years.
Best,
Éanna
