The Federal government has mandated that all states implement Appraisal Management (AMC) licensing procedures within 3 years beginning in 2010. Many states have already implemented licensing requirements making it illegal to conduct services in their state without a license. Be sure your AMC is licensed in each state before accepting work from them.
States not listed below have not finalized their licensing requirements. Landmark assigns orders in all 50 states, Puerto Rico and the US Virgin Islands.
