Ihald an H1B approved petition.However i have yet not received the petition hard copy and can travel to USA on L2 since my Husband is already in USA on L1.Can i apply for a fresh petition from USA under cap exemption without the petition hard copy?Currently i only have the petition receipt number with me.
IMO, you should be able to do that. USCIS can gather whatever information they need from the receipt number. However, prospective employers want to see hard copy to be sure that it is indeed you who got the approval notice. Otherwise they have to rely on your word.
