> How FB would know about it? In a matter of fact GDPR applies to people in EU, and data processed in EU.

It also states that data from people in EU has to be processed and stored in the EU.

It's not a matter of citizenship nor residency. Facebook just geo-locate you IP endpoint (so endpoint of your VPN) and manage your data by doing so. So USA rules will apply.

BUT if you are browsing websites hosted in Europe, EU rules will apply to your data.
