USCIS case status: receipt numbers, status messages and card tracking

Check an I-765, I-140, H-4 EAD or other USCIS case by receipt number, understand IOE and service-center receipts, decode every status message, and track the card to your door.

Begin with the case status tracking guide, then use the receipt-number and EAD card guides when a number will not work or a card is late. The I-140 and H-4 guides cover the cases that follow OPT.
