There wouldn't be an exception to the requirement for four years of physical presence under the bill. That is a requirement under the bill; however, it would be four years of physical presence out of a six-year window. Those who have to travel quite a bit for their work or for family reasons would have the flexibility to use the full two years out of the six-year window however they choose over that six-year period for times that they may need to be away. That would accommodate people in all kinds of lines of work.
