Hey people,

I need some advice on filing tax for 2009. I came here
almost 3 years ago and have been filing 1040 form for the past 2 years (2007
and 2008). I worked as a Graduate Research Assistant during those 2 years and
the amount of tax withheld was about 700-800 USD for both years. I also received
250 USD from the stimulus package (Bush ko pala ma).

I’m now sure that I should have filed a different tax form.
So, my question to those who are familiar with this is as follows;

1.      
Should I file 1040NR or 1040NR-EZ?  BTW, I’m single and in 2009 I was on a paid internship
(during CPT).

2.      
When I file the correct form this year, how much
do you think (approx) should I have to pay for the back taxes?

Thank you so much for your time and considerations.

Regards,
