My wife is in US on L1B visa, which visa is more appropriate for me to visit her L2 or B2?

My wife is in US on L1B visa.

  1. I wanted to visit her next month, so that we could travel (tour) to some places in US, before she returns to India. Which visa is more appropriate for me to visit her L2 or B2?
  2. Later incase if her work assignments gets extended I would then like to apply for L2 and travel to US.
    Considering the above 2 possibilities is it OK to apply for L2 visa today?

You don’t have a choice here. Spouse of a non-immigrant visa holder (J-1, F-1, L-1, H-1B) must apply for the dependent class in the same visa category. L-2 is the only class available to you. Applying for B-1/B-2 will cause your application to be returned with a request to correct category positioning.
