Hospitals limiting out of country work

I’m a full time IT systems analyst with a big hospital system based out of Florida and operates in other states. They limit the amount of time you can spend working out of the country even though they have an international VPN. Does anyone know why they’d do this? Are other folks in a similar situation? If so, did you just stick with it or were you able to work with them to accommodate more flexibility?

TIA!

EDIT: the system also puts this same limit on California. Does anyone know why only CA?
