I-864 concerns

[GinFar 0]

Ok, here's my concern. We sent my husband's AOS this week with the new I-864, and even though for the last 3 years tax returns, I didn't have enough supporting income, I do NOW, and I sent a letter from my employer with copies of my pay for the last 3 months also ( the three months in which I have been making sufficient income plus about $6,000 when considering what's required in a year). For 2003 and 2004, the income tax returns were filed jointly with my EX, but 2005 was just mine, although not sufficient income, so for the I-129, I had my sister as a co-sponsor. I was told it's not necessary now that I'm making enough. I sent all the income tax forms and W-2s for the last 3 years as well as the proof of my current income like I said, so does anyone think we'll get an RFE for this, or even refused because I haven't had had this increase in wages long enough? I just need some opinions if anyone can tell me from experience.
