Totally agree with BIJU as I have done the same for my MOTHER IN LAW yesterday. They told her that your result will be available at IMMIGRATION OFFICE after 3 working days.
.
Just present them PP# or VISA paper(1 month) or your receipt from MEDICAL COMMISSION and they will know the result
.
If passed, you will get extension as per ur will and if not they will deport the visitor but this time as per their WILL. LOLZZZ
