[IWantOut] 21F Healthcare US-> anywhere

I (21F) am currently a US citizen, I want to travel and eventually move to another country permanently. I’m currently in school for medical assisting at an accredited online institute. I plan to start nursing school through and accredited institution in may of this year, where I will graduate with BSN the beginning of 2026. I currently work at private urgent care. While in school I want to travel since the school is predominantly online. The three countries I’m most interested in (if I can do all three even better!) are S. Korea, New Zealand, and Australia. What resources are there, what are the requirements, and how can I obtain a seasonal working visa in each of these countries. I’d also love to know how/where can I use my degree once I graduate, or even while I only have my medical assisting certification. I know there is a lot in this post so TIA!!!!!
