'a teacher of English' or 'an English teacher'

[Richard]

As far as I'm aware:
A teacher of English=Someone who teaches English regardless of his/her nationality
An English teacher=Someone who is a teacher and is English
Am I right?
What are the differences between 'Teacher of English' and 'an English teacher'?
Can they be identical in some cases?

Hi Richard,

To be absolutely clear it would be best to describe someone as a teacher of English if you just wanted to talk about what their job was. In a context where you are talking about teachers in a school and explaining what each one teaches, it would be appropriate to say English teacher/science teacher/music teacher or whatever.
