Hey, welcome to the forum, can you tell us when did you filed your application, how was your interview and what questions did they asked ? some applicants got on spot visa and for some applicants they had returned passports, photos and again send an e-mail to submit passport, what is you e-cas showing now ? Also it depends on expiry of medical report, if medical report is expiring soon, they will ask us to redo medicals and submit it along with your passport, I hope this help you, good luck and wish you speedy visa.
