That's is so hard to find. I have contacted many expert on taxes even trough turbo tax and I still doesn't get a straight answer. One send me to his inmigration lawyer, the lawyer says she doesn't have the answer, that is a tax question. Talk to a few different tax experts and they all say differents things. He seems to doesn't qualify for eather form. He hasn't meet the substantial presence test, since he only have been for a year in US and he doesn't qualify for the 1040RN because he doesn't have a visa or workpermit.
But lawyer says he have to filled and pay his taxes.
