Until

@Mohamed A.Siead posted:

If we used the past perfect and the past simple, it would be

“He hadn’t met a native English speaker until he visited London.”

Is it possible to use future simple and present simple?And if it is possible how the sentence would be.

Hello, Mohamed—Yes, you can phrase the sentence using those tenses:

• He will not meet a native English speaker until he visits London.

Thank you.

Dear sir,

Concerning my sentence

He hadn’t met a native English speaker until he visited London.

Is it ok to say, ‘He didn’t meet a native English speaker until he visited London.’?And if not? Why not?

Thanks in advance.
