You need a valid social security number or ITIN number for tax filing purposes. If you enter as a student and still you are a student you are eligible to apply for a social security number.

if you have ss number you can file as us resident and can enjoy the refunds but the catch is it may affect on your green card if you are planning for it.

If you are planning to apply for green card then better go to file as non resident
