dont worry...you want to collect it to extend visit visa of your wife...i guess !

so once the medical is done after 2/3 working days, go to immigration office directly. you dont need medical report for visit visa. in my case same day we got message from MATRASH that medical is okay and we could proceed for visa extension. if you are not registered in MATRASH do it on www.moi.gov.in and go to e-services. coz its quite helpful
