Is getting a work visa then quitting a possibility to stay long-term? (For Colombia)

In Colombia, I have heard people telling me that once you have a work visa you can enter and not care about what happen if you get fired.
Unlike the USA where if you lose your job, you are *****ed.
Is it a possibility to get a job, get in, open a bank account(not sure if that’s a good idea since it’s not going to receive a consistent flow of cash from a Colombian company), then quit and work as a freelance remote.
