Extras din site-ul USCISului:
You are required to provide proof of employment and a photocopy or an Internal Revenue Service-issued transcript of your complete Federal income tax return for your most recent tax year. If you were not required to file a tax return for your most recent tax year, you must provide an explanation. Failure to provide the tax return or evidence establishing that you were not required to file will delay action on your relative's application for permanent residence and, if not provided, will result in denial of an immigrant visa or adjustment of status.
You may also, at your option, submit a photocopy or an Internal Revenue Service-issued transcript of your complete Federal income tax returns for your second and third most recent tax years if you believe these additional tax returns may help you establish the ability to maintain your household income at the governing threshold set forth in Form I-864P, Poverty Guidelines.

Asa ca nu este nici-un "better safe than sorry" aici. Daca ai venit suficient ca sa nu apara vreo intrebare, nu este necesar decat ultimul an.
The only real security in life is to be very good at what you do.
