老師您好，
我為我的父母在今年6月份的時候辦理了延期，但是最近無奈一再買不到第一次延期失效前（2021.1）合適的機票（很多機票都被賣完了，而且價錢特別的貴），我可以為他們再申請一次延期嗎？
-Yes. Just file I-539 and provide the copy of I-539 Receipt Notice from the pending I-539 filing.
理由是買不到合適的機票和機票費用太高，請求暫緩一點時間。這樣會有什麽不好的結果嗎？-hard to say. Don't say the air ticket is expensive, but say you are unable to get the air ticket due to Covid 19 which results in most airlines cancel the flights between US and China.
我到現在還沒有得到我父母第一次延期時的批準信，隻拿到了USCIS的Receipt。
