Thanks @DaveF1006
I read the document shared .It says"Generally, neither you nor your spouse can claim tax treaty benefits as a resident of a foreign country for a tax year for which the choice is in effect."
Please confirm if my understanding is correct
Does it mean that if I go for married filling jointly and treat my non resident ailen spouse as resident then she will not get foreign tax credit for taxes paid in CANADA ?
If yes ,then i think I should not go for Married Filling Jointly as it will lead to double taxation of her wages she earned in Canada.
