Spectators won't be allowed, though swimmers who need assistance can apply for a companion pass (by July 16), and family and friends can volunteer as timers or lap counters to get a front row seat.
Coaches of a participating club may be eligible for an all-session credential based on the number of participants their club has in the meet. Here are more details. 
The USMS Coaches Committee also assigns on-deck coaches each day of the meet as a service to all meet participants to help with starts, pace times, and directions. On-deck coaches can register now. A free T-shirt and hospitality pass will be provided on the day(s) coaches volunteer.
Swimmers: If you’re traveling without a coach and have questions, look for our friendly volunteer on-deck coaches in Greensboro. They’ll be wearing bright neon T-shirts.
