They requested copies of every page of my passport, including the blank ones, and specified that the photos must show the date and time. To comply with this, I downloaded an app that adds a timestamp to the photos.
​They also asked me to explain how I intend to support myself financially and what my plans are after the 6-month course, given that the visa is valid for five years.
​Additionally, they instructed the gym to resend the same package I had already submitted earlier, and requested a screenshot of it to facilitate their processing
I am pretty much in the same situation. I submitted my application on the 10th and the additional documents on the 13th. If I remember correctly, the status changed to pending approval on the 16th... still waiting for the decision here
