Who do you hire to help emigrate to another country? A lawyer?

We've looked into moving to another country legally, but JFC it's complicated. I guess we're looking for help with the process. I'm retired but my spouse is still working remotely and will travel back to the US several times a year. I was tasked with trying to figure out if it's feasible, what's involved for us and our two dogs. what's the process, how much will it cost, what are the monetary requirements to be a citizen in the country we choose, the application process, are we even eligible, etc. Trying to get out of the US is a huge hassle so I can only imagine what a hassle it is to legally enter the US. But that's not my problem right now. Is a lawyer the person? What do I even google to find local help emigrating?
