Moving abroad (amgevita)

Hi! I’m 24 years old and have struggled with psoriasis since before I can remember. I’ve been prescribed amgevita for the past year and a bit and it has done wonders for my skin, I really have no complaints - especially after struggling with methotrexate! Recently my boyfriend has been mentioning maybe moving abroad when the world goes back to normal, I’m all for this idea but my only concern would be my medicine. I know every country is different but does anyone have experience moving abroad while being prescribed a long term medication? Where did you move to? Was it is easy to see a dermatologist? Were medication/dermatologist visits expensive? Apologies for all the questions but I’d love to get some different perspectives on this!
