Will I need to provide documentation of all of my declared work experience when submitting my EE app, or will it be sufficient to just prove my 3+ years of foreign work experience? I ask because some of my jobs will be a real hassle to get documentation for - one of the companies I worked for no longer exists, and a lot of my work has been freelance/ self-employed which will require dealing with an accountant or something to prove. Obviously if I don't need to prove ALL my work experience, I'd rather just submit the documents for the several years of easy, straightforward jobs.
