L1 to H1 Please respond ASAP

I am currently on L1.
If an H1 petition is filed(and later approved hopefully) for me, will the L1 be invalidated if I do not stamp the H1 visa on the passport?.
I do not want to file the H1 if just filing it will impact my L1 in any way, since I might chose to be on the L1 rather than H1.
Also will there be any issues on travelling on L1, with H1 filed or approved.
Thanks in advance
