Hello, My H1B extension is filed on Thursday last week, and my I-94 expires tomorrow. There is no confirmation received that USCIS has received my file. My concern due to above situation are below - 1) As file is already been sent, Am I eligible to stay in USA post I-94 expiry ? 2) Am I authorized to start working even before I receive Receipt of filing from USCIS Could you please help with me above... Thanks. Reddy.
