I am in the same boat. Similar to the question "We had extended the visitor visa which expires soon, we haven't heard back from USCIS yet and it have been 5 months since we sent the application. If we cannot leave after the extension has expired, what would be the next step, what would be the consequence?"

Can we apply for another extension before the approval of this one or not? Because the extension was only for 6 months, which is expiring soon, even they approve it.

Any suggestions or thoughts is appreciated....
