@sonusarath , based on your earlier responses , I have provided answers. Talking about 1040.com is beyond my knowledge ( having never used and/or heard about their product & services ). My personal belief is , that in dealings with IRS and/or State taxing authorities, Immigration, US Courts etc. , that unless I am absolutely familiar with the subject, I would much rather stay with well known products and services --- saving a few bucks now may cost a lot downstream. My strongest advice would be to stay with well known providers ( unless of course you are quite familiar with tax laws for Non-Resident Aliens and Resident Aliens for tax purposes ).
