Hi everyone,
Here is an update on our progress in case anyone else goes through something similar or was interested :) :
We are almost a month in to the kidney transplant process and Mr. Daisy has undergone the transplant evaluation and is -barring complications from the single remaining exam Monday- ready for transplant and to be listed! The medical expedite for a tourist visa for his siblings is done by going in to the B2 application in ustraveldocs (on a desktop, not a phone - at least not on my phone as of 12/23) and selecting "emergency request". The requirements on that website state:
Medical Emergency
Purpose of travel is to obtain emergency medical care, to accompany a relative or employer for emergency medical care, or to travel to be with an immediate family member (mother, father, brother, sister, child, grandparent, or grandchild) undergoing emergency medical care in the United States. Required proof: A letter from the doctor who is treating or will treat you or your loved one. The letter must describe the medical condition and the urgency of the situation. You must also present evidence of your relationship to the sick or injured person.
The medical letter is relatively easy to write - we have piles of medical things. The "evidence of your relationship to the sick or injured person" - Could this be as simple as sibling's birth certificate and Mr. Daisy's, both showing the same parents? I am coming from K1 "evidence of relationship" where I included a TON of things, so that seems too easy.
