k-1 visa - I-134 tax return question for self employed

[iona.anjali 0]

Hello! I am preparing a k-1 visa application for my German fiance and I (American) and wanted to ask some advice on the income requirements. I am self-employed and in 2016 made just above the 125% mark (about $21,000) which would be the net income on my taxes, which I am working on filing now. This should be fine for the I-134 but I am a bit nervous about when it comes time for adjustment of status and the I-184. My business is really small (sewing) and the previous year's tax return shows a very low income because I invested pretty much everything back into the business for it to grow. Could this be a major issue, not having 3 years showing a steady income at the 125% mark? Does this increase the chances of needing a co-sponsor? I am confident that I will be able to show I am maintaining a steady income through 2017 (if / when we are approved we wouldn't be filing for AOS until late fall or winter even) so that would almost be 2 years and it would be clear the income is increasing. I live with my parents on their property so I have nothing else to show for property / bonds / life insurance / etc. - just about $10,000 in personal assets aside from showing this income and a few thousand dollars in the bank. The main thing is hoping this is enough for the I-134 to start with!! Any advice or thoughts on this would be much appreciated, if anyone else has dealt with something similar as far as a lower income, self-employment or less than 3 tax returns. Thank you so much!!
