Anyone from Vermont centre saw the status update online or received the updated I797?
Also, is it safe to go for Dropbox with the 1B1 error? Since USCIS is already aware of the error.. would this not have been communicated to the Consulates yet? Ideally there should be a circular to all Consulates explaining this scenario so that many people like us are not impacted in the transition till they take their own sweet time to send the updated document.
