United States soccer league system
The United States soccer league system is a series of professional and amateur soccer leagues based, in whole or in part, in the United States. Sometimes called the American soccer pyramid, teams and leagues are not linked by the system of promotion and relegation typical in soccer elsewhere. Instead, the United States Soccer Federation (USSF) defines professional leagues in three levels, called divisions, with all other leagues sanctioned by the USSF not having an official designated level or division.
For practical and historical reasons, some teams from Bermuda, Canada, and Puerto Rico (considered a separate country by FIFA) can also compete in these leagues. However, these teams are not eligible for the U.S. Open Cup and cannot represent the United States in the CONCACAF Champions League because they are not affiliated with U.S. Soccer.
Structure[]
No professional league in any of the major pro sports leagues in the U.S. or Canada, including the professional soccer leagues, currently uses a system of promotion and relegation.[1] The country's governing body for the sport, the United States Soccer Federation (also known as the USSF or U.S. Soccer), oversees the league system and is responsible for sanctioning professional leagues. The leagues themselves are responsible for admitting and administering individual teams. Amateur soccer in the United States is regulated by the United States Adult Soccer Association (USASA), the only amateur soccer organization sanctioned by the USSF. Automatic promotion and relegation between its leagues, as exists in many other national league systems, was considered by United Soccer League, but was never implemented; although voluntary promotion and relegation has occurred.[2] Some amateur leagues sanctioned by the USASA also use promotion and relegation systems within multiple levels of their leagues. However, there has never been a merit-based promotion system offered to the USASA's "national" leagues, the NPSL and League Two.
College soccer in the United States is sanctioned by bodies outside the direct control of the USSF, the most important of which is the National Collegiate Athletic Association (NCAA). See NCAA Division I women's soccer programs, NCAA Division I men's soccer programs, and NCAA Division II men's soccer programs for a list of college soccer programs in the United States.

League specifics[]
Men's Division I[]
Ownership requirements
- League must have a minimum of 12 teams to apply. By year three, the league must have a minimum of 14 teams

Financial viability
- The league must demonstrate adequate financial viability to ensure continued operation on a season-by-season basis either in the form of a performance bond or similar instrument for each team in the amount of US$1 million or readily available league funds representing US$1 million
- The maximum amount of readily available league funds for covering teams operations is US$20 million
- Any team whose performance bond is used during the season will be required to replenish it at least 120 days prior to the next season
- Each team ownership group must demonstrate the financial capacity to operate the team for five years. As part of the process of demonstrating financial capacity, each ownership group must provide detailed financial history (if applicable) and projections (including a detailed budget) for the team to the Federation in a form satisfactory to the Federation. In addition, each team must have and its governing legal documents must designate one principal owner with a controlling interest who owns at least 35% of the team and has authority to bind the team. Such principal owner must have an individual net worth of at least forty million US dollars (US$40,000,000) exclusive of the value of his/her ownership in the league or team and his/her primary personal residence. The principal owner, together with all other owners, must have a combined individual net worth of at least seventy million US dollars (US$70,000,000) exclusive of the value of ownership interests in the league or team and primary personal residences. Federation shall have the right to require an independent audit to establish that the team meets these net worth requirements; the cost of such audit shall be the responsibility of the team or league. The Federation will take reasonable steps to protect from disclosure and limit access to financial information provided under this section

Professional leagues[]
Division | League | Abbreviation | Teams | Founded | First season |
---|---|---|---|---|---|
I | Major League Soccer | MLS | 27 | 1993 | 1996 |
II | USL Championship | USLC | 31 | 2010 | 2011 |
III | USL League One | USL1 | 12 | 2017 | 2019 |
National Independent Soccer Association | NISA | 9 | 2017 | 2019–20 |
Since 1996, Major League Soccer (MLS) has been the only sanctioned USSF Division I men's outdoor soccer league in the United States. MLS has grown from 10 teams in 1996 to 27 teams as of the 2021 season. It will further expand to 30 teams by the 2023 season.
The USL Championship (USLC) is the only sanctioned Division II men's outdoor soccer league as of 2018. Formed in 2010 as a result of the merger of the former USL First Division and USL Second Division, the USL Championship was sanctioned as Division III league from 2011 to 2016 before becoming provisionally sanctioned as a Division II league for 2017,[5] and receiving full Division II sanctioning in 2018.[6]
The USL Championship expanded almost three-fold since its first season in 2011 to include 35 teams in the 2020 season, with the league divided into two conferences, Eastern and Western. After that season, held amid the backdrop of the COVID-19 pandemic, five teams left the league. Two were withdrawn by their MLS parent sides, a third voluntarily dropped to USL League One, another folded entirely, and one other side chose to shut down in favor of a future MLS team in its city. One new team joined for the 2021 season. Even at its current membership, the USL Championship is the largest Division II professional league in the world, and alongside its clubs has invested almost $1 billion into new stadium projects over the past decade to provide greater infrastructure for its clubs and fans. Since 2014, valuation of USL Championship clubs have increased five-fold. In revenue, 2018 Championship clubs saw a 28% increase over 2017 numbers on an average of ticketing, sponsorship, merchandise, and ancillary revenue generation.
The USL Championship also holds a broadcast agreement with ESPN that sees 20 regular season games televised nationally on ESPN2, ESPNews and ESPN Deportes in addition to national broadcast of the USL Championship Final, which in 2019 was aired on both ESPN2 and ESPN Deportes. The league's remaining regular season games are broadcast nationally on ESPN+, with 22 of the Championship's clubs also holding local broadcast agreements. The USL Championship's broadcast agreement was made possible in large part by a major investment by USL with league technology partner Vista Worldlink to establish a state-of-the-art USL Broadcast Center out of Fort Lauderdale, Fla.. In 2018, the Championship produced more than 575 matches and became a key component of the launch of the ESPN+ streaming service – for which it produces more live professional soccer matches than any other professional soccer organization – when it became available in April 2018.
The evolution of USL has seen the organization voluntarily recognize of the USL Player’s Association as the exclusive bargaining representative of the USL Championship's players, which will help to continue to raise the standards across the board.
The previously Division II North American Soccer League (NASL) was formed in 2009, but did not debut until 2011 following the controversial 2010 season that saw neither the USL First Division nor the NASL receive Division II sanctioning from the USSF, resulting in the temporary USSF Division 2 Pro League. NASL was sanctioned as a Division II league from 2011 to 2016; when it fielded 8 teams for the 2017 season, U.S. Soccer only granted the league provisional sanctioning as it fell under the 12-team requirement.[7] The USSF rejected the NASL's application to maintain provisional Division II status for the 2018 season as the NASL did not present a plan[8] on how it would meet the Division II criteria.[9] In response, the NASL filed "a federal antitrust suit against the U.S. Soccer Federation"[10] in an attempt to force USSF to drop all Division designations. Due to the continuing litigation against U.S. Soccer, the NASL then had to postpone its season to August 2018 and lost four more teams in the process.
This section needs to be updated.(February 2020) |
In March 2017, United Soccer League, announced following the sanctioning of the USL Championship as a Division II league it would start a new tier in its professional structure.[11][12] USL League One received sanctioning in December 2018 and conducted its first season in 2019 with 10 teams. The seven independent clubs averaged 2,496 fans per match in 2019. The league expanded to include 12 teams for its second season in 2020 and further expansion had been planned prior to the 2021 season, but was delayed until 2022 or later by COVID-19.
A second league, National Independent Soccer Association (NISA) led by former Chicago Fire general manager Peter Wilt, planned on fielding 8 to 10 teams in 2019 and has stated that it would seek Division III certification.[13] Unlike MLS, the USLC, and USL1, the NISA plays a fall-to-spring season spanning two calendar years and split into halves.
In September 2015, it was reported that the USSF was proposing the addition of eligibility requirements for sanctioned Division I soccer leagues, including that they must have at least 16 teams, stadiums with a capacity of at least 15,000, and at least 75% of the teams must be in cities that have a population of at least 2 million.[14]
In 2018, the National Premier Soccer League (NPSL), a nationwide semi-professional league announced the intention to set up a professional division, NPSL Pro. As part of the announcement, NPSL initiated a single season competition, the NPSL Founders Cup, involving 11 teams that will form the new professional league in 2020. Although explicitly a professional league, there has been no confirmation that NPSL intend to apply for DIII status.[15]

Semi-professional and amateur leagues[]
The USSF does not officially recognize distinctions beyond the three professional divisions above. Currently, all other leagues are sanctioned by USASA which is a national association member of the USSF and the only[17] member of the Adult Council. Among leagues sanctioned by USASA, USL League Two (USL2) and National Premier Soccer League (NPSL) are recognized in practical terms as playing at a higher level as both are considered national leagues and receive more automatic berths to the US Open Cup than the total given to all the regional leagues and the USASA state association leagues combined.[18][failed verification] Additionally, USL2 and NPSL pay some of their players and are more accurately described as semi-professional leagues.[citation needed]
USL League Two takes place during the summer months, and has age restrictions.[19] Thus, the player pool is drawn mainly from NCAA college soccer players seeking to continue playing high level soccer during their summer break, while still maintaining their college eligibility.[20] The National Premier Soccer League is similar to USL2 and also attracts top amateur talent from around the United States. However, unlike USL2, the NPSL does not have any age limits or restrictions, thus incorporating both college players and former professional players.[citation needed]
Men's league structure[]
The table below shows the current structure of the system. For each division, its official name, sponsorship name, number of clubs and conferences/divisions are given. The United States Soccer Federation regulates the standards for a league or division to be recognized as professional, while also determining the level of division for each league.[3]

- USASA National Amateur Cup – amateur-only cup tournament
- Hank Steinbrecher Cup – contested between the league winners of NPSL, League Two, USASA Open Cup and USASA Amateur Cup
Women[]
The Women's United Soccer Association started playing in 2001, but suspended operations in 2003. It was replaced in 2009 with Women's Professional Soccer. WPS closed after the 2011 season due to a dispute with owners, and the WPSL Elite League was the de facto top tier of women's soccer in 2012. In November 2012 the National Women's Soccer League, sponsored by the United States Soccer Federation, the Canadian Soccer Association and the Mexican Football Federation was announced.[24] The league started play in April 2013. Mexico withdrew from sponsorship of the NWSL once it established its own women's league in 2017.
For many years, there were two leagues that acted as an unofficial lower division. The United Soccer Leagues ran the W-League from 1995 to 2015.[25][26] The Women's Premier Soccer League (WPSL) was founded in 1998.[27] Almost immediately following the demise of the W-League, United Women's Soccer was founded with orphan W-League teams and WPSL breakaways.[28] UWS then formed a U23 reserve league, UWS2, in early 2020.[29]
After the 2019 FIFA Women's World Cup, USL began exploring the idea of creating a professional league to directly compete with NWSL. [30] This effort ultimately was scaled back to running an amateur revival of the W-League, which would operate beneath the DII WISL (operated by NISA) and a planned DIII league run by UWS. [31] The USL W League was official revived in June 2021.[32]
While there was never official distinction between the national amateur leagues, it was commonly assumed that the W-League was a higher quality than WPSL.[citation needed] Two W-League teams had effectively promoted into the first division – the Buffalo Flash becoming the Western New York Flash in 2011 and D.C. United Women becoming the Washington Spirit in 2013 – while no WPSL teams have ever done so. UWS, as W-League's spiritual successor, has strengthened this image of being the higher-quality amateur league by attracting four teams that had been associated with WPSL Elite.
