My wife and I obtained permanet US resiency in Jan this year.We returned to SA in order to position ourselves for the move eg selling our property and obtaining employment. On our return we found out that my wife is pregnant which has delayed our immigration plans significantly. Her due date is 5 October 2012 which leaves us with very liitle time (about two months) before a year has elapsed. In the event that we are unable to immigrate within this year - what are our prospects of obtaing a returning resident visa ?
