请问您是否了解，由两年绿卡转十年绿卡期间，去年收到移民局通知旧绿卡延期18个月。近期准备去美国境外度假，需要办理任何手续吗？
-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.
谢谢您！
