I was required to have an EKG prior to going and to have a doctor verify my health. Since I had only recently completed a physical, the EKG was no problem. They also wanted a signed doctor statement and rather than go to the trouble of seeing my doctor again, I simply signed my brother-in-law’s name and sent that. I don’t see why not. He was an air force medic in the early ‘70’s. No problem.
The lady in the picture was my Russian doc and other than a blood pressure test and eye chart exam along with a few questions, I was deemed good to go.
