Filed a Form I-539 and and the 240 days are almost up and no answer from uscis? What to do now?

It is difficult to say what will happen if you leave the US at this point. I assume that you filed for a six-month extension or 180 days. USCIS believes that if the intended period of stay exceeds the time that you are requesting, you should file an application to extend even if the first application is still pending. Perhaps the better route at this time would be to file for a late extension before leaving the country. Generally a person leaving the US during the time of a pending extension would have no problems, but I am not sure that the answer holds for someone leaving the country where he or she has already exceeded the time requested on the pending extension.
