I applied for a study permit at the Visa office in Lahore, Pakistan on June 21st. I had done my medical upfront on June 10 and submitted a paper application. Here is my timeline:
Upfront Medical: June 10
Paper Submission of application at local VFS: June 21
Biometric enrollment: June 21
Linked online Application: June 25
Medical Status updated to passed: June 26
Medical Requested: July 7
Then when I logged in again on June 28, the medical passed just went away and it shows: You do not need a medical exam. We will send you a message if this changes
Now on my online account, I have received a medical request from IRCC and have 30 days. I contacted my local physician's office and they said my medical is valid for 12 months and I don't need another one. I also filled out a webform and sent an email as well to the abu dhabi office (both which can take about 3-4 weeks to receive a response even if they do).
