8老師您好！非常感謝長期在這裏解答問題。
這裏請教8老師一個父母綠卡問題
我們是在父母B2簽證延期，I-94過期而I-539pending期間給父母提交了綠卡申請。現在綠卡已經收到幾個月了，今天收到了I-539的denial。
本來覺得拿到綠卡之後I-539的申請應該已經無關了，但是讀到denial letter最後的warning concerning unlawful presence和overstay warning，還是覺得有些擔心，想問問是否需要做什麽。這些文字盡管很可能是generic的，但是看起來觸目驚心啊。。。特別是那個overstay warning，還提到NTA的可能性，如下：
The evidence of record shows that, when you filed your application（這個指B2延期的申請）, you were lawfully present in the United States. Your period of authorized stay has expired.
You are not authorized to remain in the United States. If you do not intend to file a motion on this decision and fail to depart the United States within 33 days of the date of this letter, USCIS may issue you a Notice to Appear and commence removal proceedings......
請問8老師，這種情況下有必要擔心可能的NTA之類的事情嗎？有什麽事情是我們現在可以做的嗎？多謝多謝！！
