Hi to everyone!! I'm looking for a PhD studies in Energy Engineering, but i don't have any English certificate.......do you know where the latter isn't required? thank you in advance

Hi RIP, I don't know the answer, but I would advise looking at available PhDs and making some enquiries:

Good luck!

hi RIP,
I'm guessing countries like Germany, Taiwan, Hong Kong, China maybe? But why not consider getting an English certificate like TOEFL. It's well worth the effort, assuming you'll get a high score. If you struggle, it will just be a couple of weeks or months. Then you take the exam and pass! Look at it this way---the English cert take you very far and your options will be much wider :-)
