at least currently these countries are mostly looking for PHDs, MDs in specialities, some engineers, but degrees in stem lower than that isnt encouraged at all. because they know there will be a job waiting the moment they set foot in those countries, but its unwise for someone with a undergraduate/MS since you would have to do much more.

i knew a white guy in my CC that “expatriated” to mexico after my semester with him in a stem class this was a long time ago, kinda wierd he even bother going to school in the CC anyways in the USA, he was gone the next semester.
