We are presently waiting for a interview date for a k-1 visa. The only documentation i have not submitted is my proof of sufficient income. Being retired, the majority of my income comes from a portfolio of investments. Each of my tax return forms from my accountant is over 25 pages. Do I have provide the entire package times three as proof. I was advised not to just submit the final cover page. How can I get a clarification what I need to provide?
