If you truly want to help your friend, then lend or give him a fistful of dollars with which to at least schedule a private consultation with an immigration lawyer to properly understand the process ahead, before some fatal mistakes are made. No none files a waiver on his/her own. Those that do without the expert guidance of an immigration attorney are doomed to fail.
