I applied for change of status from L1 to B2 (since I lost my job and needed 10 days more to arrange my leaving of the country). Left US after these 10 days while application is pending and sent withdrawal of my application fro home country. I have B1/B2 visa in my passport which I got 3 years ago, can I still use it in my next entrance? Was it cancelled due to written above?

How many days... exactly?
