What reciprocity actually gets you
Reciprocity is not a licence transfer. Where California grants it, the effect is usually that CSLB — C-20 Warm-Air Heating, Ventilating and Air-Conditioning waives part of the examination for someone already licensed and in good standing elsewhere. You still submit a California application, and the state's other conditions still apply.
