My brother is helping me with I 134 as a joint sponsor. However, his situation is a little complicated. He is self-employed, but pays himself wages so he has dual income from wages and business. He files a joint tax return with his wife. When I'm filling out the section the "financial information" section, I will list him, his wife, and his two kids. I don't know what to put for "Contribution to beneficiary annually" for him and his wife (its a joint tax return). Should I put anything for his wife because that makes her another sponsor? What so I put for "Total Income". The same as the tax transcripts? But that includes both wages and business profits (some of the businesses are under his wife's name). I'm definitely confused. Any help would be greatly appreciated.
