I would like to make sure Casablanca, Morocco consulate is Appointment Post Embassy. if yes my wife in Morocco will have to send the original, Photocopy, and Translations of all the below documents with her DS-230, then latter she will need to provide the same documents to the Embassy at the day of the interview? also can she just make certify copies of all this documents so she wouldn't have to order them again and spend time and money translating them?

1)Marriage certificate,
2)Police Certificate,
3)Four Passport size photos
4)passport biographic page (Photocopy)
5)birth certificate

I also would like to know if I will need any of her documents over here in the US?
