My H1B petition has been approved. I received from the employer:
the original I-797 action notice.
copy of the contract between my employer and company X.
copy of letter from my company’s attorney stating that company X is the vendor for company Y (client) and my employer is the sub-contractor to provide consultancy services for company X.
Apart from above I do not have any document. For visa interview please let me know:
a) what other documents are needed?
b) I plan to apply for H4 visas for my wife and son along with my H1 visa, and appear for visa interview together. Is this OK, or any suggestions? Also, any other documents required for H4?
Thanks and regards,
