hoons, how are things going? I have Crohn's too and am planning on emigrating to Australia, so of course, trying to figure out the best route. My doctor put me on Infliximab (aka Remicade/Revellex) almost a year ago now and from all the research that I've done, it's fairly apparent that there is no way I would get PR whilst on medication that costs $15k a year (I guess, no surprises there). As a result I'm going to be going off the Infliximab first chance I can get to see my specialist; there are other, less expensive ways of controlling this condition. Of course, with a temporary visa like a 457, Medicaid wouldn't be paying for your meds, but that would mean that you would have to pay for them (not sure if you could get insurance that would agree to pay from the get-go - I doubt it).
