According to the law, the length of residence in initial reception centers is a period of up to six months. At the moment, the actual period depends on the state of your asylum process.
If you come from a safe country of origin as Albania, Bosnia and Hercegovina, Ghana, Kosovo, Macedonia, Montenegro, Senegal or Serbia, there is only a small chance of your asylum application being recognized. In this case, you usually remain in the federal state reception center until the asylum procedure has been concluded.
