This page is for young people in the United States looking for more information about Esperanto.
The best place for you to find out more is at the 
United States Esperanta Junularo (USEJ) website.
Does the USEJ membership work with the ELNA membership the same as the TEJO membership with UEA?
According to my knowledge, if your 30 or under and a member of ELNA, you are automatically a member of USEJ.
