I'm very sorry to hear about your wife's refusal mark. I know how you and the wife feel right now co'z I've been through it 2 times before. There were many nights when I couldn't sleep and eat after I learned about the refusal but at the end of the day I realized It's only one of GOD's trials to test us. Please tell your wife all will be okay, It was the ECO's mistake not yours. I still wonder why other people has to decide whether we will be together with our loved ones or not. Please follow the advice of what other members gave already, A letter of reconsideration might do it. Keep your head up and think positive despite of the refusal and tell the wife, 'This too shall pass'. Godbless!
