If you're deferred permanently, would it be able to be reconsidered to remove it

I've been permanently deferred 27 times. Just go to one of their other centers. Tell them it was a mistake. The person who deferred you was just jealous, a hater.

You would need to contact the center directly for circumstances. I was permanently deferred at one time for liver enzymes, but when I called years later after losing weight they said their policy on that had changed and they no longer deferred for it and lifted the ban.
