Hi BryannaYour dad was tested for TB. These tests can take time. IRCC/panel physician can request for additional tests and/or a course of medicines if there is a reason for concern or just to be double sure there's no reason for concern.
There's nothing you can do. Do keep checking the 'Medicals' status. He will hopefully get a passport request in a couple of weeks after he passes these medical tests
I just wanted to share my update just in case if you have any suggestion. I contacted the visa office as my dad's online status is showing "your action is required" even after the confirmation from PP that he sent the test report.
I heard back from the visa office that the test report is still pending for Medical Officer's review. They couldn't confirm the estimated date for finalization of this application process however, confirmed that the processing is proceeding.
Do you think I should send any further communication to Regional Medical Office (New Delhi)?
Thanks for sharing your knowledge.
