Hello dear @Kaur,
thank you for sharing your question with the Wefugees Community.
First, you should find for yourself an Ausbildung. If you have already found an Ausbildung for yourself, the the institution or the company, in which you will be doing your Ausbildung should write a letter of acceptance (Zusage) for you. Then, you should bring this letter of acceptance to the Foreigners Office (Ausländerbehörde) and there you should apply for the permission and if it is accepted by the Ausländerbehörde, based on your Ausbildung you will be provided with an Ausbildungsduldung.
