Below are the events in the chronological order for my immigration situation.
Apr 3, 2017: H1B Extension/Renewal Filed by the employer
Sep 27, 2017: I-129 and I-94 Expired
Oct 18, 2017: Last Day with the employer
Oct 19, 2017: COS from H1B to H4 Filed
In the meantime, pending H1B extension petition was withdrawn.
Dec 26, 2017: H4 EAD Filed
~ Mar 27, 2018: 6 months from the I-94 expiry
Aug 11, 2018: My spouse I-129 and I-94 expire
My question is:
If my H4 COS is not approved by Mar 27, 2018, would my stay in the US beyond Mar 27, 2018, be legal?
