Sorry you guys were refused, it's the worst feeling. But you can win appeal.
This is your appeal, reply and tell them you will be there.
You will be receiving a summons in the mail.
You need to work on preparing your proof of relationship. This includes photos, boarding passes, join bank accounts or any of the like. Shared financial dependence. Such as money gram, western union. However I did not include ours. Phone bills, some printouts of skype/messenger conversations.
You need to answer to refusal reasons. What are they? Make 3 copies. One for yourself and one for CSBA and one for the IAD in the region your under. You have 20 days I believe to submit your evidence or they won't accept it. Also you need 2- 60 min calling cards. To call your husband, or if he with you list him as a witness and attend hearing together. Sometimes they don't call. Its good for more testimony. I would suggest you read back about a year or so in this thread. You will learn alot from that. There is a list of about 64 questions that ppl say be prepared fo both of you to answer. They won't ask all but some important ones. If you can't find them, do a search. I should be able to inbox you maybe tomorrow.
I will also inbox you the contact addresses and phone numbers of all Regions for IAD. And you can take notice of yours.
