There's no point in having it and not uploading it. The validity of it is from the date listed on the check, not when it's uploaded. So if one has it, they may as well upload it. Waiting for it to be requested just causes an unnecessary delay.You can always apply and have it, just don't upload it until a case officer asks. They only give you 28 days to have it or a receipt that you have tried to get it.
