Actually it depends on the status at the end of the of the year.  Yyou may want to attach the 1040NR as the statment to the 1040.  See Publication 519 page 34: Resident at end of year. You must file Form
1040 if you are a dual-status taxpayer who becomes a resident during the year and who is 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 nonresident. You can use Form 1040NR or
Form 1040NR-EZ as the statement, but be sure
to mark “Dual-Status Statement” across the top.
