Confused again! Please help!

I finally got a response back from Frankfurt Embassy and they told me:

"In regard to your question about qualifying for an affidavit of support, if your 2011 W-2 and IRS 1040 show that you earned at least $18,387 at the same job that you had in October, 2011, you can scan and email, or fax, it to us. That would qualify. Your joint sponsor did not qualify because part of his income was from unemployment benefits, which cannot be used in this context."

So with that being said, I do have the same job as I did in October 2011. However, the highest amount reflected on my taxes is obviously the adjusted gross income which is 15,840. I would assume from what they wrote to me that the $18,387 that is required of me would be before taxes...right?

Another question if I may....Once in AP is additional proof of a bonifide marriage ever allowed if the marriage is under investigation or is though to possibly be a fraud?

As always thank you in advance for all your suggestions and help you offer, God Bless
