I am currently on L1 visa and filing H1B with COS on 1 April but i need to travel from 5 April to 20 April . Is there any possible problem with the travel , keeping the fact in mind that 1 - 94 number will change and COS approval will hold old number
i highly recomend that you postpone your travel until the change of status to H1B is finalized. You just want to eliminate any confusion or risk in the process of COS while you are out of the U.S.

The first thing is that if you have an attorney handling it, then this is a question to be posed with that attorney. This is the reason you hire an attorney. However, without going into detail, if the H-1B application is pending when you depart the United States (which seems likely) then DHS takes the position that the request to change status is abandoned. The H-1B petition can still be approved, but it should be consulate processed (I assume after October 1).
