When filing affidativ of support I-864 http://www.uscis.gov/files/form/i-864.pdf, the sponsor needs to attach a copy of federal tax return of the most recent year. What if the most recent year tax return will be available only at the end of January 2011, but the applicant's visa expires in December 2010, so documents need to be submitted before expiration. The second most recent tax returns for 2009 are not as good as those for 2010 - less income - so would it be better than to mail the tax returns for 2009 and then send later or bring to the interview tax return for 2010 when it is available. Wouldn't this 2009 tax return disqualify the sponsor? When does the immigration make the final decision on the qualification of the sponsor? Husband is the sponsor.
