I skipped the recommended in-person interview in Tennessee to save money and was on a plane less than three weeks after my initial call. Due to miscommunication, the people at LCP hadn't been notified that I was coming. There is no arbitrary length of stay.
Volunteers can come for a day or for years.
What work you do and work schedules are equally flexible. LCW and LCP are non-denominational Christian organizations, but volunteers are not required to be Christian. All that is necessary is a sincere desire to help children in need. There is no budget for the volunteer program. Other than receiving free lodging, volunteers must be entirely self-supporting.
