It is good that you want to earn your own money. In Germany, you can begin working even during the asylum procedure. The time until you are allowed to start working is between three and nine months. The foreigners authority will tell you when you are allowed to start work. You should definitely use the waiting period to learn the basics of the German language.
Make good use of the waiting period
This is a great advantage if you then apply for a work permit. You can also use the waiting time to gather information or visit a company that is looking for staff. You can also complete a work placement very quickly after your arrival and registration. This increases your chances of finding a real job.
