Does 2nd visit on B1 visa need a new invitation letter?

[randsg]

Hi,

 

I have a B1 visa with 10 years validity. I visited USA from India on this visa about 9 months ago. When I visited USA first time, I used the same client invitation letter which was given to me at the time of my visa interview.

 

I have to visit USA again in a few days. Will I need a new client/parent company invitation letter for this 2nd trip? Or, can I travel without any letter this time?

 

Regards,

Ram

Better to carry a new letter as it might be requested at POE.
