UK to US nursing

There are a bunch of existing threads here about UK nurses getting (or failing to get) licensed in the US. Lots of info there. Have you had a look?

Yes but it is complicated because most of them are UK citizens trying to get residency and trying to transfer their license. Where I have citizenship in both locations. Maybe it would be best talking to the state board of nursing where I live and asking if they are familiar with the topic?

They are likely to tell you that they can't tell you anything until you have a nursing degree transcript that can be evaluated for its equivalency to US nursing education, but it can't hurt to ask. And citizenship has nothing to do with licensure. Regardless of your US citizenship, if you study nursing in the UK (or anywhere else outside the US), you will be an "internationally educated nurse" when you return to the US, seeking initial licensure, and you will remain an IEN for the rest of your career. There's nothing you can do once you're back here that will change that. There will be extra paperwork and hoops to jump through for initial licensure, and any time you apply for licensure in a new US state in the future. There are known difficulties with UK-educated nurses getting US licensure, because, as you already noted, the UK uses an entirely different model of nursing education and licensure, and there are v. few places in the US that you can complete the additional required education. US nursing programs are limited by the BON as to how many students they can enroll, and most of them stay fully enrolled with students who are completing the entire nursing program. They rarely have extra "slots" to allow someone to enroll to take just one or two nursing classes. It's either the whole program, or nothing.
