How do I process W-2 Tax return when I'm outside of the country(u.s.)?

Question

I'm going back to Japan in this months.

I've worked this year(2008) for about 7months.

I'm not a citizen nor resident of United States.

Am I eligible to get tax return in 2009?

In that case, should I tell the company HR my foreign address?

Answer 1

Use foreign postage stamps. Mail your return to Austin, Texas. Keep a US bank account open if you have a refund.

Answer 2

You should file. You may be entitled to a refund if you paid in more than your taxes.  

Answer 3

You will need to file a US tax return.  Whether you will get a refund or not cannot be determined with the information you provided.

Your HR dept. should be able to help you.
