Let's try this one more time ----
(1) US citizen/Resident(Green Card ) / Resident for tax purposes all file using form 1040 and taxed on your WORLD income i.e. income from all sources domestic and foreign.
(2) Unless the Resident for Tax purposes ( i.e. NOT an immigrant per USICS ) wishes to take advantage of Treaty benefits , there is NO purpose/requirement for IRS to ask for your citizenship or immigration status. The only reason IRS asks for such information on forms 8831,8841,8843 etc. is to ascertain that the taxpayer's claim of treaty benefit is legitimate. USCIS does not administer tax treaty conditions/ benefits
(3) If you are a Non-Resident Alien ( non-work visas like F, J, etc. ) and have not passed the Substantial Presence , Test you are taxed ONLY on your US sourced / connected income and you report this on form 1040-NR or 1040-NR-EZ. Both of these forms require you to provide your immigration information such country of citizenship, type of visa, passport details etc. etc. Not that you CANNOT use TurboTax to file such returns.
In summary , while I will refrain from commenting on this referred article, the requirement to report your immigration information is NOT true --- from your contacts with the Immigration Dept, they are saying NO and yet this rumor persists. Please people, stop amplifying this false rumor. TurboTax and all other tax service providers all will tell you the same thing.
I stand down.
