The option for invite users is visible for some users, for example:
However, for another users, this button doesn’t exist.
What is the rule for this button?
They must earn trust level 2 or higher.

Trust level 2 is very easy to attain. It’s reasonable to expect someone to be TL2 before they invite others. If they’re really desperate to introduce others before there’s always the “register” button.
