my son has serious heart problem because of Kawasaki disease. He follows his treatment in Algeria, in parallel I am in contact with a Canadian expert on this rare disease. I read on a more complicated case than my son who is well groomed and out of danger by the same doctor. I do not know how to do to accelerate the process to obtain a temporary visa or special visa -if exist- to look after my son. Please, it's very urgent. guide me how to do please.
