I am from Lebanon. How exactly does the regulation with the age work? Am I allowed to start an apprenticeship when I am 25 years old or older? Is there an age-limit at university?
You can study at any age. But going to university does not extend the residence permit status. Apprenticeships do so because they are linked to a certain profession and the idea is that you will work in that field later on. Studies, in contrast, are too unspecific and are not leading directly to a particular job.
Yes, you are allowed to start an apprenticeship or studies at university.
You are from Lebanon so the chances to get a positive result are probably quite low. That is why I highly recommend to start studies or an apprenticeship. The only requirement that needs to be fulfilled for that is that you got a permission for that in your secondary regulations. Then you can search for a company that offers you a training. The Duldung for Ausbildung does not give any age limits.
When you are from a country where the chances of getting a positive decision on your asylum seeking process are low than I would highly recommend to start an apprenticeship.
And what do you think about which type of work is fitting best for me? Which factors should I take into consideration and what happens to the money that I get from the jobcenter or the Lageso?
