I don't know but if to do one more medical test is not a problem for you, I suggest to do it in case requested in future again. sometime they don't do that right now. like my 1st FBI's PCC (expired), if they asked me to renew it when they received my application, it won't delayed my case for almost 3 months. After the application submission, I was thinking they bought it, because after the expiration date, I have never been to US, logically there would be no chance for me to have a criminal background while not in States. That's why I submitted a expired PCC along with the application. Unfortunately, they realized that half year later, just because of expiration. I had to take 2 more months to prepare a new PCC. It doesn't make any sense, but I have no choice.
