Do you get any GCMS Notes for the first and second refusal? Did you reapply with your family on the third application? May be you should wait until get all three GCMS Notes.
The timelines for the applications I have submitted are as follows:
First application for whole family submitted on 16 May and refused on 29 Sep
Second application for whole family submitted on 7 Oct (added my own fixed assets and CA report ) and refused on 21 Oct (GCMS notes requested)
Third application for just me submitted on 24 Oct and refused on 25 Nov
Fourth application submitted just for me few days back after rephrasing the SOP. This time under Non SDS.
The reason for refusal was always the same (Purpose of visit not consistent...…..)
My PhD admission was deferred from Sep to Jan. I may also request GCMS for third application but it would not be processed by Jan and I am not sure if university would defer by admission further. Hence, waiting for decision on 4th application and/or admission deferral. It has been a terrible experience so far.
