Try to give Call Centre a call first thing in the morning. After passing security questions, the agent might be able to send it to your email; he/she definitely has access and visibility on the correspondence I can confirm that. You actually should have received correspondence via email if you filled out one in the application form that is. I suggest you better have this sorted out now. You don't want to receive any correspondences by snail mails. Reference: personal experience, also was requested for docs on Jun 10th, request sent to sponsors email.Anyone can help advise what does it mean, am I going to receive anything by mail(nothing reveived till now...). Tks..
"We sent you correspondence on June 10th, If you have not yet provided the information or the requested documents, please do so as soon as possible. Please wait until you receive the correspondence before sending us additional information, as the correspondence will outline all information that is required."
