Host the United States will face New Zealand in the Rugby Sevens World Series semi-final in Las Vegas after impressing on the second day of competition in front of a record crowd of 34,593.
Current Series leaders South Africa will face Fiji in the second semi-final.
The US began the second day of action with a 19-19 draw with the South Africans in the final pool match before coasting past their North American rivals Canada 20-0 in the quarter-final phase.
They will now target a second ever appearance in a Sevens World Series final and one of their try scorers in the quarter-final Danny Barrett was pleased with their last eight match.
"We couldn't have started in a better way," he said.
"It's always our goal to keep an opponent to zero and it's a tribute to how hard the boys work week in week out.
"We're ready to give it a go against New Zealand and see what happens."
Their semi-final opponents New Zealand tasted defeat in their final pool phase match but bounced back in the quarter-finals, as a Joe Webber hat-trick saw them overcome their rivals Australia 28-5.
South Africa booked their place in the semi-final stage with a 21-14 victory over England, who had progressed to the quarter-finals after a difficult final pool match against Kenya.
South Africa will be hoping to continue their impressive record in Las Vegas as they are seeking their third consecutive triumph in the American leg of the Sevens World Series.
Like England, France had to secure qualification to the last eight phase earlier in the day, winning their final Pool D match 26-7 over Brazil to advance as runners up, but they met their match against Fiji, with the Pacific Islanders winning 31-12 in their quarter-final match.
Fiji, New Zealand and South Africa will extend their advantage over the chasing pack in the overall standings with the top four spots guaranteeing a place at the Rio 2016 Olympics, while the US will put themselves in the mix with their performance in Las Vegas.
