回复：请教各位大虾， EB2 140 RFE一般会要什么补件?

If you are applying for NIW,Usually, they ask you to provide more evidence such as reference letters, more papers,awards,citings, another cover letter telling them how strong your case is, and so on. So, you need resend almost all the documents again.Although it is scary,However, after they receive your REF documents, they commonly approve your case.So don`t worry and good luck.
