Deductions & credits

Thanks @pk  To answer your question: I've work permit in Canada and I will consult some tax professionals for taking care of taxes on Canada side.

Only things that I'm not sure about is when I fill 1040 for period (Jan-Oct) Do I need to file as married filing separately? or should I file as usual married filing jointly? Also, How would this work for 1040NR for period Nov-Dec?
