Hi guys, I've been self employed since 2014. I'm reading that I have to prove last 10 years of employment? I can provide articles of incorporation and contracts for most years, but I don't have the contracts for first couple of years. What should I submit? Tax forms? Is it okay to submit contracts for some years and tax forms for another few years? And what about that reference letter? I'm reading that it's necessary and if I don't provide it they may return my application. Do I have to write reference letter for myself as a business owner or what? And what if I'm not able to get reference letters from employers before 2014?
