CIS is a little ambiguous about H1 "status" after AP use, but reading cronin memo, it can be interpretted using AP will terminate H1 status(this does not necessary mean one can not work under H1. that is what this memo clarified). Until H1 extension is filed which is considered "reinstating H1 status", one remains as a parolee.
