California's 104 NP license opened January 1, 2026, and the rules are not what most PMHNPs assume. The practice authority is real, but the qualification path has teeth — three years of full-time NP experience minimum, a population-of-focus that has to match your boards, and a transition period that's tripping people up before they even apply. This Deep Dive walks through the 104 NP pathway from a PMHNP's perspective: what counts as qualifying experience, how the population focus rule works for psych NPs, the practical steps to file (and the documents that get rejected most), and what happens to your existing supervised practice while the application is pending. If you're a PMHNP in California — or thinking of moving there — this is the breakdown to hear before you write a check. Based on the full guide at psychnpfellowship.com/california-104-np-pat ...
