Hello Experts - My H1-B and my wife’s H4/H4-EAD stamped until Sep 09 2019 (Expired now). However, My H1-B is renewed till March 2022 via premium, but My wife’s H4 & H4-EAD petition is still under process (received appointment notice for bio metrics). And she applied for H1-B (2020 CAP) in April, and it is approved till Dec'31 2019 (her H1-B status will start from Oct 01, 2019). Isuue. 1) If her H4 and H4-EAD approves before her H1-B expiry date (Dec'31 2019), What status will she be applicable? (Will her status change from H1-B to H4 automatically?) 2) Let's say if she doesn't apply for H1-B extension and her H4/ H4-EAD is still under process/ approved after Dec 2019, will she be continued to stay on H4 status legally? 3) Is there a way can we check whether her H1-B started from Oct 01, 2019?
