I think you are dual status alien for the year 2005. Here is the information about how to file the tax return for the dual status aliens. Hope that helps.

Resident Alien vs. Nonresident Alien

The U.S. income tax return you must file as a dual-status alien depends on whether you are a resident alien or a nonresident alien at the end of the tax year.

Resident Alien at End of Year

You must file Form 1040, U.S. Individual Income Tax Return 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, U.S. Nonresident Alien Income Tax Return or Form 1040NR-EZ, U.S. Income Tax Return for Certain Nonresident Aliens With No Dependents as the statement, but be sure to mark "Dual-Status Statement" across the top.

Nonresident at End of Year

You must file Form 1040NR, U.S. Nonresident Alien Income Tax Return or Form 1040NR-EZ, U.S. Income Tax Return for Certain Nonresident Aliens With No Dependents 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.
