It's worrying me because every singe successful case I read the wording of the email is different, stating that the visa "has been issued" instead of just processed. Maybe I'm being a bit paranoid...Subject: Your Visa Application
Has been processed. Your documents will shortly be despatched. We want to hear your views on the service we provided...
The only reason I can find for a refusal is that they require the funds in the bank statements to be "consecutive 28 day period (finishing on the date of the closing balance) ending no more than 1 month before your application". My statements ended 1 month before I submitted my ONLINE application but were older than a month before they received the paper application with biometrics and other documents.
Would this be a sufficient reason to get refused the visa? Also, should I worry that the email doesn't mention it has been ISSUED?
I'm really nervous as I'm supposed to start my course in less than two weeks

Thanks in advance.
