What is wrong with you paranoid wussies? If no one is getting the form then it's not being sent out and why would anyone complicate the matter by sending in a form that wasn't sent to them to be returned? If you're so worried about this form then you should probably go back to the US and join the rest of the sheeple still there so you won't have to deal with this again.
Seriously, if this was just a case of one or two not receiving the damn form, then those are the ones that need to be concerned. However, if you're still getting your funds, then stop with the drama. Nine pages on this topic is pure BS so grow a pair and get on with your life. The world may in fact be coming to an end but not because the SSA did not send you your 7172.
