B1/B2 Visa Clarification

[haresh_srm]

Hi,
I have been living in the US from 2000 to 2006 mid and relocated back to India after that. I entered as a student (F1) and then was working on H1.

Last year(2007) I came to the consulate in Chennai for a Business VISA as my company needed to send me to the US for a business conference. I got 10 years multiple entry B1/B2 VISA and I visited US last year for a month

Now I am just wondering whether I can use the same B1/B2 VISA issued by the consulate last year to visit my friends this year "just as a tourist"(leisure travel). Basically I want to visit for a couple of weeks on my own. Or should I apply for a new visitor VISA for me to travel as a tourist?

Also what kind of documents should I carry for my travel?

Thanks in advance

Since you have a B1/B2 visa, you can use it to enter US for leisure too. an invitation from your friend should be good enough.
