My wife went for the medicals and they asked for an EMI number. We haven't received such a number other than the AOR1. And on the AOR1's bottom of the first page there's a 'Requirement for Medical Examination". That's why she went to get it done. And they're asking for an EMI number. What is that? Can someone please tell me what an EMI number is? She is at the hospital right about now.
