Since your case was filed as "Counselor Processing" the USCIS will send a copy of the approval notice to the consulate in Nepal. In the mean time they will also send the approval notice (I-797 document) to your employer who will then send the following to you so that you can go and apply for your H-1B visa.
Invitation Letter
I-797 (Approval notice)
ETA-9035 (Labor certification)
I-129 (Forms)
Then you will need to prepare the following for visa interview:
•Visa Application Form DS-156 (males complete DS-157)
Go To:
http://kathmandu.usembassy.gov/ •Passport
•A recent photograph, with signature on the back
Go To:
http://travel.state.gov/pdf/Photo%20Guide%2010-01-04.pdf •Original degrees
•Original I-797 Approval Notice....you will receive from your company
•Copy of the H-1B petition (Form I-129)...you will receive from your company
•Copy of the certified Labor Condition Application (LCA)...you will receive from your co.
•An original, current letter from your company confirming your offer of employment
If you have a spouse/dependent then they can also apply for an H-4 visa.
Hope your questions are answered! Good Luck and welcome to the USA!
