Dear @Anna Igbinosa,
thank you for sharing your question with us.
As for your question:
- once you come back to Germany you can file a second asylum claim- please make sure you can proof that you didnt receive the letter by the court( e.g. the camp you lived can write something or you write an Eideststaatliche Erkärung).
- then the process will start again and this time make sure if you move to give the new address to all authorities Auslönderbehörde, BAMF, Court in person and get a Eingangsbestätgung.
- In case you will need personal assistance in the entire process please look out for the local Flüchtlingsrat they can assist you in these cases.
I hope this can help you, if you need further guidance please do not hesitate to reach out to us.
