各位大侠，
我的I-140 NIW已经批了, I-140 OUTSTANDING need REF。现在准备自己办485. I-485表中，有一个问题,请各位大侠赐教:
I485 part3 A ---
Have you ever before applied for permanent resident status in the U.S?
Yes or No？
If Yes, 是否我应该把我的两个140 申请列在表中？
另外，我在为我老公填I-864表 （他是H1B），同样有一个问题:
I864 Part 2. Basis for filing affidavit of support.
I am filing this affidavit of support because (check one):
a. I filed/am filing the alien relative petition.
b. I filed/am filing an alien worker petition on behalf of the intending immigrant, who is related to me as my _______(relationship).
a or b ?
另外，自己办I485，所有的photocopy是否需要公证？例如出生公证，护照，I94 …
不胜感激！
