H1b Stamping time and documents


I recently got my H1b approved by USCIS. I got my masters degree from US and was subsequently hired by a Big 4 accounting firm.My company has over 30K employees in the country itself. My work would involve travel and project assignments with some of the biggest companies in US. How do I provide Client letters from them? Also , Is December a good time for Visa Stamping?

Client letters are not required when working for such big firms. Client letters are asked from small-medium size firms to establish regular inflow of funds and hence their ability to pay the salary. With big firms, its not a concern.

Talk to your attorney about the job description and then carry information/documents about the same.
