COS from L1b to H1b

Hi,

I have L1-B visa until Oct’16 but I have received I-94 till July’15 because of my old passport expiry. This year on April’15, I have filed for COS from L1B to H1B and in the same month I have traveled to Mexico Border for my I-94 extension (before H1B lottery result declaration) after receiving new passport.

Can you please let me know, is their any impact on COS due to Mexico Border travel or not.

Thanks in advance
