If one applies for a FSW as a cook for example, how will authorities check for that authenticity. Will they call up my employer (restuarant), require documents to verify that I have worked as a cook, require tax documents etc? Thanks in advance.
Certificate/s of Employment for one; Tax Returns/Documents (right); Certificate of Completion/Training from School/University. I don't know if ever the Visa Officers actually do call employers/authorities. The burden of proof is on you because if they doubt the veracity/authenticity of your documents then they can just turn down your application.
