Hello, dear Dcooper,
if you are registered by the Agentur für Arbeit it is your obligation to be present on the terms you receive from them. That has nothing to do with the deportation. They want to see your which profession you have and what did you work in your land you come from or in Germany. It is an option, that they will offer you vacancies and you will be asked to write applications in order to work.
The language course you (maybe) get promoted is a vocational language course. That can nobody answer if it be rejected or approved. It is a decision of BAMF.
I hope that the answer can be helpful to you.
