Yes, the $100K fee exists and applies under certain circumstances, essentially if the beneficiary is outside the U.S. or ineligible for a change of status or change of employer. Most companies are simply not pursuing H-1B petitions where the $100K fee would apply but there are exceptions.

It's possible to extend H-1B status beyond the 6-year max-out period if the beneficiary is in the green card process. But if the beneficiary isn't in the green card process, then the most common option is the O-1 and while it's getting harder to get an O-1, it's still within reach of many talented professionals and founders.
