Thanks for sharing your experience my wife got an interview in November and they also requested the following:
Birth Cert, Marriage cert, pictures for our marriage, proof of communicationi such as phone bills, email,picture and she was also ask to bring her school documents,birth cert or previous passport. I don't think you should worry cos accra is one of those VO that can ask anything they want and believe me the pictures you sent from your doctor will help a lot. My only advice is if your husband is sending them his school cert let him attached that with some pictures he took at the school during his school days if he has one. Good luck and all the best
