I had submitted Form 5406 online because I thought I forgot the city and zipcode for my brother.
Anyhow, I finally got an email back and they said that they can't attach that document, that I would just have to send it again after it's rejected.
Hopefully I corrected that form before I sent it and just forgot to save it. But, otherwise I'll be sending my application again after it gets rejected.
Thanks for letting the group know.
What about sending another package now with the same receipt of payment to get a place in line just in case?
