My goal for learning Esperanto
Here is my goal- Linguistics, Teaching and learning other languages. Want to earn a degree in English/English Education as a foundation for teaching Esperanto.
You certainly don't need a degree in English to teach Esperanto. As you might expect teaching the language is an an important part of Esperanto culture.
if you want to learn to teach Esperanto there is an association of Esperanto teachers http://interl.amu.edu.pl/interlingvistiko/index.html
The Internacia Esperanto-Instituto also trains Esperanto teachers https://www.iei.nl/
