8老师，您好，我曾多次请教您问题，每次都能得到您的指点和帮助，非常感谢！！
我的情况：我已绿卡，现准备递交I 824 follow to join为国内的爱人办理绿卡。
现有一问题：I-824表需要递交“A copy of the original application or petition that you used to apply for immigrant status ”，我的理解，是递交一份我以前申请I485材料的复印件。
我以前申请I-485材料的Checklist，如下：
1. Copy of immigrant petition approval notice or filing receipt (I-140）;
2. Two recent identical 2”X2” passport style color photos;
3. Medical exam report I-693 and supplement (sealed);
4. Copy of your latest paycheck stubs (past 3 months) or current employment verification letter;
5. Copy of your federal tax return forms for the past 3 years;
6. Copy of passport photo page, U.S. visa, I-94, approval notices of all extension and/or change of status in the U.S. (I-797), and all supporting documents of legal status in the U.S. (e.g. I-20, IAP-66, DS-2019);
7. Copy of I-612 J-1 waiver approval notice if you have been in J-1/J-2 status;
8. Copy of marriage certificate, if married ;
9. Copy of your birth certificate.
请教的问题是：是否以上当年递交I485的所有材料，from 1-9，都需要再复印一份递交用于I824 follow to join的申请？
还是只需要从中挑几个必需材料复印用于I824？如果是这样，哪几样是必需的？请指点。
有些材料，如Copy of your latest paycheck stubs (past 3 months) or current employment verification letter; Copy of your federal tax return forms for the past 3 years;那都是申请485之间的好几年的，现在再复印递交用于I824 follow to join，我觉得可能没有什么意义。请指正。
谢谢您，有劳辛苦了！
