I think if online aaya medical request sent then you can get the meds done and your meds will be sent against your file number. No need to wait for the letter I suppose.we are all waiting but Abu Dhabi visa office is sleeping somewhere.
as on 25th June 2018 i got update on my online account that they sent me medial request but i never got any medical request so far. But online status says that they sent me Medical request...Nor me nor my representative nor online account has any letter for medical request letter..
now waiting!
