My mother came to US on visitor visa, her I94 expired but i filed the extension much before that. When the case was under USCIS review, she had to go back to India and on airport handed over expired I94. The extension came later, and i have new I94 with me(valid). Since she left US on expired I94(which shows that she overstayed), she may have troubles coming back. Can i submit the renewed I94 somewhere ? so that the record gets updated. What shall I do ?
