My EAD was approved, but because of the mistake of the postoffice, the EAD card was returned to VSC. I called the VSC, they said they will mail it back to me, but it will take about one month that I receive the card. Currently I am waiting for the EAD to start working in a company, is there anything I can do before I actually receive the card? Since my EAD is approved, can I just start working at anytime? Will infopass be useful in this situation? Thanks for your help.
