請問您是否了解，由兩年綠卡轉十年綠卡期間，去年收到移民局通知舊綠卡延期18個月。近期準備去美國境外度假，需要辦理任何手續嗎？
-No. Bring your conditional green card and the I-751 Receipt Notice which states that your conditional green card extended for another 18 months with you. You also need to return to US before the 18-month extension expires or within one year, whichever is earlier.
謝謝您！
