@Alex ********
I followed the list that's on their website. I called a few times but nobody answered. Therefore I just followed their form on their application page. Was I supposed to concise documents in 1 PDF and submit it there?
I remember there were 3 sections for PDF submissions, one was asking for employment contract or letter, one for financial evidence, and another one for something else. Where was I supposed to submit my work invoices and other items? Proof of income was in my financial statements.
