If you were a Resident Alien at End of Year:

You must file Form 1040, Write "Dual‐Status Return" across the top of the return. Attach a statement to your return to show the income for the part of the year you are a non‐ resident. You can use Form 1040NR, U.S. Nonresident Alien Income Tax Return as the statement, but be sure to mark "Dual‐Status Statement" across the top.

If you were a Non‐resident at End of Year:

You must file Form 1040NR, U.S. Nonresident Alien Income Tax Return if you are a dual‐ status taxpayer who gives up residence in the United States during the year and who is not a U.S. resident on the last day of the tax year. Write "Dual‐Status Return" across the top of the return. Attach a statement to your return to show the income for the part of the year you are a resident. You can use Form 1040, U.S. Individual Income Tax Return as the statement, but be sure to mark "Dual‐Status Statement" across the top.

Hi thanks for the input. I understand that process, but it does not mention how I sum up the refunds- I have $X from 1040 NR and $Y from 1040.  I ended the year being a Resident. S0 1040 is my dual status return, and 1040 NR is my statement.

Where do I put the sum ($X+$Y), if anywhere? Or do I not have to sum the refund amounts at all? 

Cheers! 

Thank you! Much appreciated!

Cheers
