There were no "further career moves" available when I worked in the Middle East either,
shiju. That was for two reasons, I suppose. One, because we were there to work, not study. And two, because we were there to work, there was hardly any time left for study anyway! The full-time academies out there are aimed (quite rightly so, in my opinion) at the citizens of that country.
May I therefore suggest you learn
here from the voice of experience. By "making hay whilst the sun shines" (ie, working hard and saving your money), you’ll be able to do what you please (for a while at least) afterwards. If that includes paying your way through whatever courses take your fancy, all well and good. There’s your plan. How does that sound?

I might add a personal note that I learned more about the realities of contracting in the engineering support and maintenance of medical equipment, and in new hospital projects, out there in the Desert than I would ever be likely to learn from a
life-time at Falfield (or wherever).
