L1B and client location

[anuraaga]

Hello,

I work for ABC company as a software developer and here in the US since July 2015 on L1B visa.  I have been working at a client location XYZ company since then, on a daily basis.  My appraisal and day to day supervision is done by my ABC company.  I have to travel to India for vacation and my visa stamp has expired.  So ABC company gave me a new petition with client information noted as its more than 50% client location work involved.  

I want to know if I would face any issues during my visa interview as US consulate since I will be using the new petition.  Will I need to carry any form of client letter to produce infront of the consul officer ?  I am yet to schedule by L1 visa interview and had concerns about the same.

Appreciate any response towards this.

Thanks.
