Dear sir/ma'am,

I am in confusing situation on B1/B2 visa's validity. Let me explain it now.

I entered U.S with B1/B2 visa and applied for F1 status change in May 2008.
It took much time to get an approval decision until April 2009.F1 status is approved!
But in that time I received a letter from my family and it was that I had to go back to my country.I left U.S while I am in F1 status, of course I made a cancellation school and study.
Now I'd like to travel U.S just to see some old buddies I made there. I got in my passport still B1/B2 visa is stamped and valid through 2018.
My question is: Is my B1/B2 visa still valid or not? I mean if it is still valid that I do not need to apply for a travel visa isn't it?

Before departing to U.S, I'd like to make clear out all my doubts.

Please, any advice, email is welcome.

Thanks in advance.

Sincerely,
Jayser.
