Dear @Arie,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
I remember that you mentioned before that your fiance is based in Waldkraiburg, right? I would recommend him to contact a so-called "Asylverfahrensberatung" (counselling on the asylum procedure) to support him in the preperation for the interview. I tried to make some research online to find a respective office close-by. However, it might be the best solution to contact the Refugee Council in Munich to get more information. Their number is 089-12390096 and he may reach them every Monday, Tuesday and Thursday from 10-12 am. You can also contact them via Mail (info@muenchner-fluechtlingsrat.de). I am sure they can also refer you to an institution or office which can advise him on his vocational training plans.
Regarding the length of the asylum procedure or waiting time, I can unfortunately not add any more information than in my response to your last question.
I hope my explanations are nevertheless useful for you and please don't hesitate to get back to us if any clarification is needed or you have any further questions.
All the best,
Meike
