Hi,
Thanks for the interest in Facebook Events.
Facebook Events can import individual events from user profiles manually. That is a limitation from Facebook and cannot be changed.
We can also import from Facebook Pages with the automatic importer.
It is a one time import and not a sync so if changes are made it does not update on your site.
Both both cases the Events have to be public and have no restrictions like age or country.
We have this guide to setting everything up that might help your review all the features:

Let me know if you have any follow up questions.
Cheers
