Terry Hiser, an aide to Rep. Elton Gallegly (R-Simi Valley), will be in the congressman's local district office from 9 a.m. to 10:30 p.m. today.
Hiser invites residents who have disputes or concerns with federal agencies to discuss them. She will also take suggestions from the public.
Open office hours happen about four times a year in Simi Valley. The rest of the time, Gallegly's representatives are located in his Oxnard office.
The visit will allow those who cannot make it to the Oxnard office a chance to be heard, said Tom Pfeifer, Gallegly's press secretary .
Hiser will be available at Simi Valley City Hall, 2929 Tapo Canyon Road.
