I'm Canadian. I work in US but live in Canada. I commute to work everyday. I have two daughters: one is 11 years old and the other is 23, who is a graduate student in US. Both live with me. I filed 1040nr every year. My questions are:
1) Can I get child tax credit and deduct daycare fee for my yonger daughter?
2) Can I deduct tax for my daughter's tuition fee?
3) Can I claim the mortgage interest of my house?
Thanks!
