Dear
@User655,
congrats to the marriage permission.
As for your question:
1. please ask the BAMF they might alreadyhave your documents from the Norwegian authorities,
2. if not you will have to ask the Norwegian authorities to return it- the best way would be ask through their embassy in Germany or if you have contacts in Norwegia through them.
I hope we could address your question, if you need further guidance please do not hesitate to reach out to us in the community.
Best regards,
Nilab
