Hello @Hattem
Nice to hear from you again.
In order to apply for asylum in Bochum you can go to the so-called "Landeserstaufnahmeeinrichtung" (reception center) at Gersteinring 50a, 44791 Bochum.
Apart from that, you can also get in touch with a police officer and tell them that you want to apply for asylum. They will refer you to the right institution.
Best regards,
Thorgen
