I think there's a place on the form, if I remember correctly, or it was in the instructions that you can have someone else fill out the form for/with you. I think you then sign as the person filling out the form...and there was a place for that.

Hang in there. It's a ridiculous process with way too much paperwork in my opinion. I was lucky enough to get it on the first try but I feel for those people who go through these mountains of paperwork only to be denied. It's not easy but don't give up...I think in many cases they want you to!
