請問，有關以前身份的文件，例如十多年前的I２０，所有H１B的元件，EAD卡，申請H１B和綠卡準備資料的複印件，我還全留著呢。在拿到綠卡後，現在要搬家了，不知道是不是還應該保留這麽一大堆東西。
-You had better keep the green card application documents such as PERM approval (if you have), I-140 approval notice, copy of your I-485, I-485 receipt and I-485 approval notice. Don't need to keep I-20, H-1, EAD, etc. if you don't want to.
