UK to US

Hi folks! My partner and I are currently long distance (US v UK) and one of us will be moving in the next couple of years. I’m currently studying for an MLitt in Archives and Records Management (ARA accredited course) in the UK and was wondering what kind of additional training, courses, etc, I might need to work in the US?

If anyone has made the move and would be able to give some insight into this and the US job market, I’d be so grateful!
