Biruwa: Your info is incomplete. 
Are you in H1B1 or Residence or F1 status? We can answer from here. You did not
know about Indian students can file tax as US Residence and can get more
refunds.

It
implies to Umesh too. I am guessing you have used 1040 and you have couple
children and you qualify for New Education credit which is up to 2500 dollars
and not completed 4 years college. If you were on F1 status, no way you will be
getting that much refund. It may mislead to them. They are hoping to get more refund
and can pay tuition.
