Hi all, new here so please bear with me. I am in category 5 and my application has been in for four years. I have not been allocated a case officer as yet but my AUS agent told me in Feb that the DIAC are security checking our application- we are in UK. At this point I have just finished social work degree and am wondering should I undergo a skills assessment with a view to submitting a fresh application or sit tight and wait it out.....any ideas or guidance would be appreciated. thanks
