recently got my h1b approved. I hired my own attorney (company paid h1b fee.) Attorney said original h1b approval notice is being mailed to company HR. I have not received anything as of yet. I will ask for the approval notice from HR.

Will I get a copy of approval notice, any other paperwork from USCIS? Will be I getting new i-94 number. what paperworks do I need to have to maintain my h1b status. During my h1b, do i need to update anything?

Help is appreciated
