Bro, you don't need to be a US citizen or green card holder to file a regular 1040. What part don't you get about doing your research correctly. Residency has a different meaning for the purpose of US Tax Return. You picking up on mom and pop tax preparer just because you know little about 1040NR proves nothing. Would you rather take small itemize deduction or just a standard deduction. Plus 1040NR doesn't give you EIC (earned income credit FYI). If you are not a lawyer or a tax expertise than you need to stop giving you advise in public forum.
