We received an RFE for my wife's I-485. We are using the concurrent filing (adustment of status) to also change her name to her married name. We filled out all forms with her new married name and we included a copy of the marriage certificate in the online I-130 application. However, in wondering why we got the I-485 asking us to redo the form, I thought perhaps we should have included a copy of the marraige certificate ALSO with the snail mail I-485 submission. Should we have included a copy of the marriage certificate with the I-485 subsmission as part of the process of changing her name (in addition to including it with the online I-130)? If the answer is yes, shoud the copy be a certified copy? We can include it in the mailed I-485 RFE response if necessary.
