Regarding I-539 denial

[immihelp]

Hello there, I arrived in the USA on February 2010, on July 2010 I applied for an extension of stay and got denied. the denial was decided on September 1st (B2 status was over August 2nd) and I found out on September 15th. I left the country on September 28th so I did not overstayed the 30 days.

My question is - to what address do I need to send my letter containing the proof I have left the country (boarding pass original denial letter explanation letter etc..)?

and also, I have read the article you have posted on the matter (a real life saver that was!) and I did not quite understand- even if I did overstay my B2 status it was because of USCIS processing , once I got the denial I left before 30 days so is my multiple entry visa still voided??

Please answer, I would really appreciate it - the reason I applied for an extension was because I have been accepted to college in the US for the Spring semester meaning I need to get my F1 visa ASAP and that would not be possible without the multiple entrance visa..

Thank you so much!

1. You don't have to send proof anywhere.
2. Yes, your visa is still void.

Thank you very much for your answer!

BTW- is it even necessary to have a multiple entrance visa if I apply and receive a student visa? I mean I could legally enter the states with only my student visa without having the multiple entrance one?

If you have a single entry visa, you can enter the U.S. only once. If you want to enter the U.S. multiple times, you need multiple entry visa.
