Hi I have been refused for entry clearance for spouse visa. As my wife doesn't earn £18600 and we had a son who is 9 years old and they are alone in the UK with no support. She can't do extra hours due to the child. We had an appeal on 6th Dec 2016 and today we got the refusal and my solicitor was asking us to file for upper tribunal which I want to file by myself. How much does it cost and what is the time frame for this and is it worth in case where you are not meeting the financial requirements??? My wife had a medical history of depression and now she again depressed.
