Hi there. I'm in the US as well and have plans to practice in Ireland at some point. It'll take a few year since I'm finishing up my MSOT program and I want to work in the states first but I found this YouTube video a while back during my research which might be of some help:

Here is the website where you can start your application for Ireland to recognize your credentials:

It can take several months. The person in the YouTube video said it took 4 months and was initially rejected due to some paperwork missing. Be organized in your approach and you should be fine.
Good luck! =)
