Hi, My husband is currently trying for a 189 Visa, he's been a self employed carpenter since 1998. During that time his work has varied from sub-contracting to working for Joe Bloggs. No 2 weeks are the same. For his skills assessment we need to write a personal statement, we obviously want to get this right first time. Has anybody written one that was accepted, if so how much info did you put in....Also client references, did you include these?? Any help would muchly be appreciated.
