Hello @Kidane - welcome to our community. Before we can give you an answer to your question we need to have a little more information about your background.
First of all, what is your legal status? Are you an acknowledged refugee, are you still in the asylum procedure or do you have Duldung?
Did you finish your studies (do you have a degree)? If yes, is it acknowledged ("Anerkennung")? Where did you do it?
Also, where do you live (which city and since when)?
Best regards, Thorgen
