Keep in mind that visa means you still need to self fund health care and in many countries like Canada and Australia if you are disabled you can be denied permanent residency for being a cost burden on their healthcare system.
Research where you go if you are disabled and leaving, especially if you’re leaving with permanent residency in mind
Oh for sure, self preservation above all. I just mentioned it because I’ve known a lot of disabled ppl who were very surprised to find that out and planning needs to start now
