@aaj,
I'm not a pych NP, but I have worked in the nursing industry (attracting nurses for nurse employers) and am a bit familiar with industry needs as a result.
As you already know, nursing employment usually isn't a problem for RNs (especially after a year of experience, they are in high demand) but in this recession there has been a bit of a hiring freeze. But even in this climate, NPs are in high demand.
So bottom line is that after you have a year of experience, you shouldn't have any difficulty getting employment in either, but NP is at even greater demand than RN and it is likely to continue this way for some time. I can't tell you much about the process of getting there, but it should improve your career prospects by making you an even more highly sought commodity.
