you would realize what a burden this is.

It's one thing stretching the deadlines to state governments, but if I do that with the feds, I may end up in Guantanamo!

I still haven't managed to get a straight answer out of any state gov't what "moving" or "residence" really means anyway.  "Well, is it your intention to stay?" they ask.  "Well, I don't know, I want to stay for the next couple of weeks, but might change my mind tommorow."  I drive 'em crazy.
