Countries with low tuition for non-EU students are on mainland Europe. I imagine English may be the only European language you speak fluently. You'll find it much easier to find work in English in a technical role than in a management role, since managers need to more often speak with customers and staff of all ages, in more roles. An MSc in some shortage technology field seems like a great option. Look at mastersportal.eu to filter schools by fees and language of instruction. Also see the DAAD.de website.

Otherwise, maybe consider options in the UK? Without speaking the national language (I'm assuming you don't speak, say, German or Swedish for example), your options are potentially more limited.

What is your budget?

Which of these MBA programs would be the best bet to transition to Europe? I speak Spanish fluently and enough French to get by day to day:

UC3M
IÉSEG
EADA
CNAM

Thank you for any advice or any other alternatives keeping in mind that budget is an issue.

EADA has much better careers support than UC3M. No point attending an average French school for a degree in English if you can't work in French.

That's good to know. If I were to take intensive French lessons over the next year so that my language skills were better, would this change your advice?
