Thank you for your reply. That's quite impressive, I've rarely ever come across someone who has studied at that many schools across so many continents! Do any of the programs you've studied at offer Bachelors in CS or Linguistics? That's what I would need first, unless there is a program to go straight through to the Master's.
I would need to pull up my notes but Univeristy of Kent, University of Sheffield, Open University, Thomas Edison, and Open Classrooms all offer CS degrees that are recognized. Again, do your own research. Sheffield and Thomas Edison both offer Master's for educated professionals without a Bachelor's. You generally have to write out a bunch of statements on why you are qualified to enroll.
You can earn an entire Bachelor's by testing out and/or doing prior learning assessements (I've thought about that if I could find a subject that interested me). PLA acceptance is far more prevalent in Europe than in the US, though Thomas Edison in US does let you test out or do PLA for the entire degree if you are capable of it. I'll point out that doing PLA is not a walk in the park. I've done a couple of prior learning assessments where I felt I knew the class subject really well - it was probably more work to do the assessment (lots of writing and gathering of research notes and documentation) than it would have been to just finish up the prescribed projects.
I am no expert in any of this, and I strongly recommend you do your own research.
