The United States Tennis Association (USTA) is the overall governing body of tennis in the United States. It is organized as a 501c (6), and the Section offices are a combination of 501 (c)(3) and 501 (c)(4) entities. Changes in USTA bylaws are considered and voted on at the USTA Annual Meeting in March and/or at the USTA Semi-Annual meeting in September. At the national level, each Section has one voting delegate, but voting power is weighted by USTA membership. In terms of membership, USTA Northern is the third smallest section.
