Defending champion Samoa is in Pool D along with host USA Eagles, Australia and Spain.
The Eagles reached the Bowl semi-finals at last year's USA Sevens and hope to improve on that in front of the home crowd.
"We look at it as returning home and using the energy of our home crowd to do good things," coach Alex Magleby said.
"That's what our crowd deserves; they deserve to see the team that represents them play with a lot of passion and execute well.
"We look forward to delivering. We're excited to be home."
It is not going to be an easy start as the Eagles will open their tournament against Australia on Friday.
