Received approval for 3 years pgwp. Applied 28th May, Approved on 19th Oct, No biometrics, inland application. Applied from Vancouver. Hope everyone gets their approval soon.
The following is going to be a letter of explanation I submitted along with my application. Keyword of my situation: part time semester in one and only one required semester, parttime, part-time, fulltime status, full-time status. I wrote the words like these just for the people in the future be able to search my comment.
Context: I started my university as a transferred student from college in 2015 Spring, because Spring is a hot semester for students to be in school, and because the enrollment system in my university, my enrollment date was fairly late. Eventually I was only able to got 2 courses while having 2 courses on waitlist(2 courses on waitlist is the maximum number of course to be waitlisting in my school). In my school, Spring and Fall are the required term, while summer can be considered a regular break.(So which term is a required term to be full time is depending on how your university define "full-time" status). Other than this semester, I was always full time(but I did take 2017 Summer off which is fine). So my letter of explanation is all about explaining why I was being part-time in Spring 2015. While enrolling courses for Spring 2015, I tried to change my entire schedule at that time to avoid being part-time. Overall, I did not blame anyone but myself for not being able to maintain a full-time status. I also learned from this incident to make backup plans for enrollment.
Content of the letter: Sincere wording, not too wordy. Mine was one page only with some formatting. My school was allowing students to retrieve their enrollment record, so I ask them for it, which acts as a supplementary document that shows that I tried not to be part-time as the position of the waitlisting courses I was in at that time was fairly close to get me to enroll and I did not drop them at all. Throughout the letter, I blamed no one because I know this is my own fault. I focus on telling what I learned from this incident(indeed this was a lesson to me) and what I have been doing to prevent myself from being a part-time status again in the past few years.
Just to share my experience here. Wish everyone gets what they want eventually. Cheers.
Edit: My experience I shared here may not be applicable to everyone, whatever I have said here only represents my own situation. Just to be clear here.
