Hi ate nivea, congratulations on your spousal visa approval and I'm sorry to hear about your son's refusal Can you tell us what was the reason for refusal? A letter of reconsideration to the ECM might do but you must also lodge your appeal. I suggest you pm Terpe about a good lawyer, I'm sure he can give you better advice on what to do. Please don't be sad, I'm sure his application will get overturned. Stay positive. 'This too shall pass'. Godbless!
