Whiting visited the Texan circuit as part of the scheduled pre-race inspection and granted the track the Grade 1 status it needs to host the Formula 1 grand prix.
Whiting had already visited the track in June. The circuit is scheduled to host its first race on November 18.
"Everything that I've seen so far has been absolutely first class, and the progress that's been made since the last time that I was here is amazing," Whiting said.
"The guys have done an awesome job - it really is quite fantastic! It's built to the highest quality, exactly as we expected, and I've got absolutely no complaints whatsoever."
Whiting believes the track will provide plenty of opportunities for overtaking.
"There are 3-4 corners that are very likely to see overtaking," Whiting added. "If you look at Turn 1, you'll see that the turns have been designed so that they're extremely wide and the apex is very short.
"It's a very modern approach to slow corners where we hope overtaking will take place. So I'm very confident it will work well.
"Turn 1 is awesome. It's the only word I can think of to describe it, and I think drivers and teams coming here for the first time will say the same thing."
Whiting will conduct the final inspection on November 12.
