Hi Emily, could I rack your brains on the back and fourth movement between Aussie and USA, we were going to move permanently this coming January 2016, after activating in Jan 2015 but I have to come back to Aussie for an unexpected eye surgery which they cannot give me a date for yet, I'm on the Queensland health waiting list they have said it will be within the next 7 months, we still plan to go over in January 2016 so we don't disrupt the permanent residency status but would like to then come back to Aussie and work whilst we wait for my surgery day probably another couple of months May/ June 2016, do you know of anyone who has gone back and forth after the first year and had any issues, the homeland security page says you can't leave for more than a year but I'm really nervous we may be stopped and questioned at the boarder, I may just be being neurotic but any helpful advice would be really appreciated
