H1b visa dropbox urgent help

[phoenix_nebula]

Guys,  I am in Client->(My Employer) EC model.

I wanted to check for dropbox , last time i went they asked for only employment confirmation letter. but Today i am checking ustravel docs website it shows like this below: 

Principal applicant’s employment  confirmation letter (original/copy) and end client letter from employer/petitioner. (Applicable for H1, H4, L1 Individual, L2)

 

I want to know if the employment confirmation letter is enough or do we need to take client letter also? please help me .. i don't have much time.

I’m in EVC, but they asked only employement verification. Safe side carry client letter as well, we never know what they ask.
