I had my visa interview yesterday at Dec 06th at the US embassy in djibouti based in marriage in which my visa has been approved and my passport has been taken advising me that it will take one week to issue the visa. However when we came back to the house and checked the returned original documents we showed to the counselor ( birth certificates, marriage certificats, .. etc) we noticed there were some papers returned to us by mistake which is a routing sheet used by officer , and the I 130 petition form with DHS stamps. I am not sure what is going on. Should I return these documents to the embassy. Will this affect my visa process since I am no at administrative processing.
