Yes, we don't have enough money saved for an attorney unfortunately. We would have waited and saved the funds but we had a loss in the family and our funds have been limited since. We did send a copy of the diploma originally and we called the USCIS to clarify everything. They said that the original would be sent back to us (I have had a similar experience when I sponsored my father to come here and I had to send my original birth certificate but had it sent back to me in a few months) and that we needed to send the original. I think for now we might try to go to the post office and see if it's possible to put the envelope on top of a box and have it taped or we'll just have to fold the diploma. Thank you again for all the responses, they are much appreciated.
