I dont't know to be honest. My meds were passed and the documents one changed to no additional documents needed. The medicals thing happened to others on tje forum though. You can do a search to find a fewHi Hamgha.
I have same status as yours. Please, i would like to know if the background check has started or not with that narration. Also, my medical exam was previously passed in June 2017 when received by Visa office but latter changed to we are reviewing your medical exam after proof of medical was requested which i have provided but it still we are reviewing your medical. Will it still change back to passed or not? What should i be expecting now? Your comment will be greatly appreciated with thanks.
