@jay23 - wala pa akong nabasa na same case as yours for EA. but i think its acceptable naman..
hindi ka ba pwede humingi ng Cert of Employment at detailed job description?
Other assessing agencies suggest the following:
(e.g. title of project, duration, tasks completed).
- proof of paid employment (Payslip, ITR, or probably Invoice as consultant)
remember, your objective is to prove that you have worked, and that work demonstrates the skills required for the nominated occupation..
