Thank you for sharing your question with the Wefugees Community!
I was not familiar with the “BO plus”, as it seems to be a regional program, which exists predominantly in Hessen, is that correct?
But I learned now, that it is kind of a short-term vocational training (usually about 4 months), which might prepare participants for a long-term vocational training or “Ausbildung”, as far as I understood.
In order to be safe from a deportation, one need to be enrolled in an “official” or acknowledged vocational training, which fulfills certain criteria and lasts at least two years (new regulation).
The immigration office (Ausländerbehörde) might issue a so-called “Ausbildungsduldung” in that case.
I am sure that it is a very good first step to absolve the BO plus, however, and as you mentioned already, it will be essential for you to make an “Ausbildung”.
Regarding the pending Asylum case of your wife and the impact on your potential deportation, it is also very difficult to give an final answer on this.
I read that Ausländerbehörden act very different in similar situations. It might also play a role if you entered the country together, applied for asylum at the same time or as soon as you both came to Germany etc.
As is in your case there are many potential factors need to be considered, I can also recommend you to seek individual legal advice. You may want to visit a migration counseling office, for example.
Please let us know if you need support in finding one in your area and don’t hesitate to get back to us with any further questions.
