I have exact same thing (number 4) on my application status...
If we r seeing number 4 in our application status is that means they sent medical request? I have this information in my file status for quite a while.... I didn't receive any letter nor the email for anything for medical...
They were asking about Schedule a form in last December and i have already provided...
4 . We sent you correspondence on December 16, 2016. 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.
This is in my status... i want to add here that same date they told in this status (16 December) i got the email to update newly filled schedule a form 2nd time ...so my confusion is that this could be for that request for Schedule a or it could be a medical request for that I didn't receive anything no email no letter...? ?
Thanks
