I switched from OH to PA and it was kind of an ordeal. Go to the PA State Board of Nursing website ( I just Googled it) and then you have to go to the Licensure Information tab. If you scroll down a little bit you’ll see an section that says endorsement (under Board Forms/Applications). I downloaded the Licensure by endorsement with temporary practice permit and mailed it in with the fee. The problem I had was that the school I went to required fewer clinical hours than the state of PA so I had to mail in verification from my employer. I don’t know if it’s usually a long process, but it took forever for my PA license to become active.
I hope this helps you some!
