My fiancé and I are just about to send off the documents for his fiancé visa application to Sheffield, but we're struggling with getting the return postage sorted. He's sending it to Sheffield (from the USA) and I think I've seen people mention on here something about setting up an account with FedEx. However we tried that and it required details such as when the parcel would be mailed, which obviously we don't know. Any ideas on how to do this?? We really need help. Another option is for me to buy the return postage in the UK but I don't know if that's possible, as we want the parcel to be trackable... Does anyone have any advice?
