From this one:
from IRCC;
- if the applicant is self-employed, articles of incorporation or other evidence of business ownership, evidence of self-employment income and documentation from third-party individuals indicating the service provided along with payment details (self-declared main duties or affidavits are not acceptable proof of self-employed work experience).
In this part, I'm thinking of the income as the business income. Is it not?
My NOC is 21300. I can provide proof of email coordination from clients. Reference letters from third-party persons I've worked with. I can also give a copy of all the drawing sets I did if it's necessary lol Contracts, tax documents, and purchase orders of the COMPANY. I'm technically a board member since that's what is written in the articles of incorporation, I have the same number of shares as my parents. I'm technically not working for my parents.. they are working with me.
Edit: I can also show proof that I used some of the money generated for my personal use. e.g. assets like buying a property under my name and using that income to pay for my studies here. Also, we have an HR, that's not my parents, that can testify and provide a reference letter.
