RDGC,
Hopefully that is all that is required by INS. I am sure your lawyer would have mentioned if they required additional info. Unless your lawyer is a total moron. I suggest you get on the ball and mail all the W2's ASAP! If you have been following this forum, there was a discussion on replying to RFE's and the consensus was to reply fast before the case moves off the IIO's desk and into the pile again. If you reply fast enough, you will receive an approval inside the next few months, otherwise it might take forever!
