L1 rejected, applying again with different skills


My L1 got rejected last year. My company is thinking of applying again. I want to change the skills and make it a more strong case as the earlier case was rejected based on the skillset being available in US.

My questions,

  1. will the rejection of older L1 has any effect on the new one?

  2. Can I go with a new set of skills in addition to the ones that were added last time?

Thank you in advance.
