How to wirte sentence?

Hi My Friends,

I have a question on the further sentence that how I could write it whether "Most of our users have difficulty speaking English"or “Most of our users have difficulty to speak English”

which one is correct? what are the difference between them ?and why?

Cheers

These are correct:

Most of our users have difficulty speaking English.

Most of our users have difficulty/difficulties in speaking English.
(Use of the plural denotes specific individual problems as opposed to a general condition.)

Offhand I cannot think of any examples where it would be correct to directly follow ‘have difficulty’ with an infinitive.

Thanks for your replied but let me know why not we are using this sentence as meaning is same “Most of our users have difficulty to speak English”

That is incorrect grammar.
