Ok, maybe I wasn´t clear enough, This is my situation
I worked at the bank in my country for 3 years, but then I quit my job and started working as self-employed in a gym. The owner hired me on February 2014, since then I have been working for him. I made his business software and I am the one who maintain this program working making updates, etc. He pays me in cash every month for my work and he gives me a receipt of monthly payment . So, he is my permanent client.
I have other clients but only occasionally
I am trying to apply under Federal Skilled Worker program and this year can give me extra points.
My questions are:
1. Could this work count as work experience?
2. If it counts; Can I present a reference letter and my receipts or should I present something else like pay of taxes?
