I was wondering if CBP simply looks at visa expiry, or whether they check the issue date in these cases. One assumes that they would trust an issued visa has met all requirements- but it would be nice to have that confirmed.
Just expiry. The person could have been issued by a waiver or exception. That's not for CBP to determine. And that answers the common question of why the order barring entry actually bars issuance.
