Good Morning and Welcome to Connect. I send your brother my thoughts and hopes for continued health and I admire his attempt to be a donor for you. And for you, @abel I send my hopes and some resources to help you with your future decisions.
In answer to your question about the amount of wait times, I refer you to the Scientific Registry of Transplant Recipients (SRTR) where you can access national data. Here are 2 articles that can help you to get started.

@abel Welcome to Connect! No doubt you are both very disappointed to receive that news, that your brother cannot donate to you. I cannot give you much information about other states, except to say each transplant center has their own criteria. You would have to go through testing again, specific to that center. If you are a veteran, check with the VA, as they will transport you to other states for a transplant. Please let us know what state you are in?

Hi @abel, Here is a blog post written by our Transplant Team answering many of the questions you ask about out-of-state transplantation at Mayo Clinic.
