Welcome back to the Wefugees Community and thank you for reaching out to us again.
I am afraid that it will be hardly possible to give you any tailored advice here without knowing your case and your background. You are right, to make an „Ausbildung“ (vocational training) requires usually a solid command of the German language. However, you should discuss with your lawyer if there are any other possibilities for you. I assume that the lawyer filed the “Berufung” as he/she knows your case best and sees a chance of winning in court. The civil servants at the immigration office may not always be right in their assumptions. For people who absolutely don’t have another chance to apply for a residence permit and who can still present a very strong reason why they have to stay/can not go back, there might be a last option of presenting the case to the hardship commission in your federal state. Please follow the link for more information on this.
However, I would strongly recommend to discuss your situation in detail with your lawyer or you may contact a migration counseling office. Please let us know if you need support in finding one in your area.
All the best,
