Applied for H4 EAD extension and yet to receive I-797C Receipt Notice. It shows online that the receipt notice is sent and its been almost 2 months. It must be missed in delivery by post office and any thoughts on how to get the copy/duplicate of this receipt notice. Appreciate your quick suggestions.
You can call USCIS and open a case to request the copy of approved notice.
If you applied online, you can download the copy of approval notice.
