Can I travel as Tourist with B1/B2 visa?

[Ranjanidove]

My organization applied B1 visa for me and its stamped as R B1/B2.

I have traveled to US 3 times for Business purpose. Now I am not employed and would like to visit my friends as Tourist.

Can I use the R B1/B2 visa for my travel as Tourist or should I apply a separate B2 visa ?

Or Should I apply I-539 to get B2 Visa?

Please advice!!

Yes, you can use that visa to travel as a tourist.
