請教老師，母親2019年9月來美，2020 年2月由於疫情辦延期，由於疫情，打指紋被延後到2020年9月24日，10月5日延期信批準延期到9月19日。我們夏天看到移民局網站上寫由於疫情原因，凡是遞交延期申請的在美人員可自動合法在美240天。我們計算應該是2020年11月19日。
-Because her application was approved, this rule does not apply to her anymore. Her illegal stay is counted from the date the I-539 application for B2 extension was approved (i.e. from October 5).
收到移民局信後，我母親看來是已經非法滯留，但整個過程1是被美國政府拖延，二是買不到回國的直飛機票。如果想要保持合法記錄，請問有什麽辦法嗎？
-Because her application ahs been approved and the I-94 has been expired, she needs to leave US as soon as possible (had better do it within 30 days). Keep the I-539 Receipt Notice and the Aapproval Notice in case she needs this documents for future B2 visa application.
