I just changed the DLI number as soon as I got admission to the new university on Feb 27th 2020. I was still registered as a full time student at my first university at that moment. I was just not doing classes. I did not give any explanation letter while applying for PGWP.Hi,
Just on reading this it seems very confusing. Did you provide a letter of explanation explaining all of this in detail? They probably denied you as they didn't understand your situation clearly enough and as they had a doubt in the validity of your application, they refused you.
