My USC wife is sponsoring me, and has only earned a qualifying salary in the most recent tax year (ie, 2004). Does this mean that, in addition to her federal returns and W-2s for 2004, for 2003 (which was a joint return with me) and for 2002 (filed before we were married), I have to file I-864A along with my relevant returns and W-2s for 2004, 2003 and 2002? OR, is only the most recent year of income used to qualify?
