My wife and I got married in mid 2015 and she is still deemed a resident of the USA while she is awaiting Permanent Residency here in Canada. She has no SIN number and has been 'visiting' me for less than 1/2 the 2015 year. She is not filing a Canadian tax return as a result and I am trying to file separately... with this annoying question.
I get a huge difference in my refund if I either use $0 for her income vs. putting in an estimated amount of $ for her US income.
Obviously I would like to get the extra refund on line 303, but want to abide by the law on this.
