Canadian Retirees Visa

It's tied to the Immigration Reform bill now stalled in process, and my take on the impasse between congress, senate and President is that it will die on the table. It would let eligible people have a 240 day visa rather than the current 180 day limit. You don't need to own US real estate, just have a permanent residence outside the US and have a rental agreement inside the US, plus a few other things of little consequence. The kicker for me would be that there is an extremely good chance that by staying that long you would become subject to US income tax law, and that would be a whole can of worms that no one wants to open...
