It is hard to understand. My understanding may be not precise.

If a person's H/L employment authorization is still valid, if he/she did not leave (the H/L sponsor), and if he/de came back with an AP, working without an EAD is legal until the final rule is published (never happen since then)

Note: only people with a 485 pending and using AP to come back will be called paroled adjustment applicant.
