My wife have valid E2 Visa (Dependent) till Fab/2023. Her I-94 expired on 10/28/2020 and I applied I539 extension for her 45days before I-94 expired. it been over 6 months we didn't get reply from USCIS, I want to know if we don't get approval over 240days. Can my wife still stay in the US until a decision...
