wow lucky you.
Any way these r the docs listed in
 http://nepal.usembassy.gov/temp_work_visa.html

When applying applicant must submit the following:

• Completed application form
• Passport valid for travel to the United States and with a validity date at least six months beyond the applicant’s intended period of stay in the United States.
• One colored photograph
• A notice of approval, Form I-797
• MRV receipt (provided by the Bank)
• Citizenship card

The following documents are required at the time of interview:

-        Approval Notice Form I-797 issued by the USCIS

-        Evidence of Employment in the U.S. (e.g., Job letter, pay stubs etc)

-        Firm Registration Documents

-        Tax documents, if any

-        Prior visas/passports

-        Academic records i.e., transcripts

-        Any other relevant documents

-        Firm registration documents in the U.S. (for L-1)

-        Citizenship card

 I'm mainly concerned about  Firm Registration Documents . Now what is that? Do we need it?

Plus, Siwani could you please let us know the availability of dates once you reach NABIL for scheduling
your appointment.

Here are some scenarios of successful visa stamping, grabbed it from murthy.com

- I did my MS in US ; I am working in US based company in USA; I went for H1B stamping in Chennai consulate
The Visa officer just asked about the nature of job thats all; then finger prints were taken and he said I will get my visa in 2 days

If u have F1 visa in ur passport H1B stamp is easier
