when I was in Joburg/when being in Joburg

[AlexAD]

Hello.

This sentence, 'I have some experience speaking English when I was in Johannesburg', sounds good to me. Do you think so?

Can I change the when part by rewriting it 'when being in Johannesburg'.
May be it is not grammatical but I am curious if I can speak that.

Regards, Alex.

You need a "from" in that sentence:

"I have some experience speaking English from when I was in Johannesburg."

"When being in Johannesburg" isn't grammatical at all.

Thank you, SlickVic9000.

And here is another question, what about have? Should it be had or may be have had? What do you think?

Regrads, Alex.

All of them have their place in this sentence. "Have" is present tense and suggests that you are talking to someone about your English speaking abilities. "Had" is past tense and indicates that this sentence is part of a larger narrative involving your proficiency with spoken English.

If you're going to use "have had" I'd change the sentence a little:

"I have had experience speaking English since my stay in Johannesburg."

I would suggest:

I have some experience in speaking English from when I lived in Johannesburg.
I gained some experience in speaking English when I lived in Johannesburg.
I have some experience in speaking English, gained from living in Johannesburg.
