Qualification
USA Track & Field sets minimum performances standards for entry into the national championships. In order to merit entry into the championships, an athlete must meet that standard, or better, within a set time frame prior to the competition. For the 10,000 m, 20,000 m race walk, and combined events the qualifying window was from January 1, 2018 – July 21, 2019. For all other events the qualifying window was June 1, 2018 – July 21, 2019. The organisers also set a maximum number of entrants and rounds for each event. There are also automatic qualifying criteria outside of the entry standards. Athletes who are the reigning indoor or outdoor national champion are automatically qualified to enter that event. Athletes who meet the "A" standard for entry into the previous Olympic Games or World Championships in Athletics receive automatic entry, as do any athletes who placed in the top three of their event at the 2018 USA Outdoor Track and Field Championships. Non-American athletes may compete as invited guests only and their performances may not count towards the national results nor international team selection. Athletes must have United States citizenship to be selected to represent the nation, else non-citizens must receive approval from the Track & Field Committee and be due to gain United States citizenship prior to the international meet that the national championships is selecting for. For events over distances from 100 m to 800 m, performances will only be accepted if fully automatic timing is used. For performances beyond that distance, FAT times are also used, but in the event that the athlete has not recorded a FAT performance, a manually recorded time may be used.
