Are there any lenders that can qualify foreign income not reported on tax returns?

I have a prospective borrower that receives foreign income from a Turkish employer for her work here in the U.S. as a Market Researcher. She is already under contract, has an appraisal and has placed earnest money on a property. This is a primary residence, a real property SFR. She has dual citizenship but this income is not claimed on her tax returns here or in Turkey. I do have bank statements for the last 6 months showing deposits from Turkey, as well as a letter from her employer and a statement from their accounting department showing the dates and amounts of each wire transfer to her bank account since last October. She has worked for this employer for the last 4 years. I need to find a lender for her because she was denied with us due to her income not qualifying. Any help is appreciated.
