Headquartered in Portland, Maine, Esperanto-USA is a 501(c)(3) nonprofit organization and the U.S. affiliate of the Universal Esperanto Association.

The organization's leadership consists of a president, vice-president, secretary, treasurer, and nine directors; it also has many commissioners responsible for Esperanto-USA's activity in various connections (e.g. audio-visual service; cooperation with libraries; relations with local Esperanto clubs; etc.).

Three years later, UEA recognized ELNA as its American section, and subsequently severed ties with EANA.

Among other reasons, the change was made because the organization's scope is limited to the U.S., despite the North America in its original title.

Notable speakers have included Humphrey Tonkin, Katalin Kovats, Duncan Charters and Bertilo Wennergren.
