sorry can't type Chinese

being in the US less than 5 years, OPT->H1B in 2006,

question 1,  file either 1040 or 1040NR, which one?

question 2, don't have to file interest income if 1040NR, and have to file interest income if 1040, true or false?

question 3, if 1040, have $5150 standard deduction, if 1040NR, have $5000 treaty deduction, but can't be both. right?

thanks
