Is it possible to get a foreign accent in your mother tongue by speaking/ teaching a foreign language a lot?

Question

Hello,
I'm French so sorry for the mistakes.
I'm a student at university and I would like to become a teacher of the English language.
My own experience tells me that language teachers do get a foreign accent when they speak their mother tongue.
So here are some questions about that:
How to get a foreign accent (I mean permanently?
I mean, if I speak English for example 4 or 5 hours a day which will happen later on when I'm a teacher, is it "enough" to get an English accent in my native language?.

And another one:
How do you get rid of a particular accent, or try to take one accent?
This counts for short changes (films...) and for definitive alterations in one's accent.
I have a German accent in French which bothers me a lot, that's why I'm asking.

Do you think it's better to keep your original accent when yu are a language teacher?

Answer 1

I think it takes a lot of constant practice. My grandfather is french but was made fun of for his accent so he sort of forced it out of him. I don't know how long it takes, but I think if you were to talk to him now you wouldn't know he was French. I think that the more you submerse yourself and force your mouth to make english sounds 100% of the time your french accent will fade.
I don't think that being an English teacher means you have to speak English as your native language. My Spanish teacher in high school was english and only spent time in Spain and Mexico and new Spanish.
