I am going to India for my wedding, I plan to do my L1A stamping and get an L2 for my wife. Now suppose my L1A stamping is denied, what happenes to my existing L1b petition which is valid till 2011 Oct? Can I use that to file and L2 for my wife and return back to US?
Your current approval is not invalidated by denial of an L-1A. You can use it.
