回复：急问：EAD上的expire date少写一年，我该怎么办

You can just continue to work If your current employer agrees. Because your OPT extension has been approved and the mistake of the OPT expiration date was USCIS's fault, technically you have been authorized to work by USCIS. But if your employer does not agree you to work, you have no choice and have to stop working.
