usually scientists have easier time moving there, than not. i dont have a PHD or MD,just had a degree in said bio/research, i know people that have similar issues even with a MS. found out through many job forums, now shut down. that it is extremely gatekeeped(2-4+years experience, with additional skills nobody has heard of), meaning the hiring pool is small so they can avoid hiring too many people lowering salaries of the scientists, being cheap.

also might difficult for people that hadnt renewed thier paspport in a very long time too.
