For me it would depend on:
How easy it would be for you to get a Visa and work. Not sure if you're married and if this makes a difference
Who you're leaving behind. Do you have family with close relationships that you see often for example
Finances. What's the cost of living and housing in the areas you want to live compared to your likely earnings? The distribution of wealth in America is a huge problem with a lot of the population in massive poverty (although the uk is heading more and more in that direction). Could you afford healthcare? If not I definitely wouldn't go, you dont want to risk being in an accident that bankrupts you or you have to choose which limb to save because you can't afford both. You want to be able to take your child to the doctor when she needs it
How close your husband actually is to friends and family. How often would you see them etc
I'd want to go there for an extended break eg two months if you can afford it, to see how you actually get on with the lifestyle and culture (eg when I've visited the states I find the drive through culture really hard to get on with, in the areas I've been to everyone drives everywhere and goes for hikes separately. I walk and cycle when I run errands to get some exercise into my day and so didnt get on with that aspect very well but wouldnt have nesseccarily thought about it beforehand)
How often can you afford (in both time and money) to come back home. what if you absolutely hate it there, would he agree to move back
How important are politics to you? I couldn't actively choose to live somewhere with laws on guns, abortions, all the hard right stuff as I fundamentally disagree with it. Other people wont disagree or wont be as bothered if they do.
What are the local employment laws eg is it fire at will, how important is job security to you. How many holidays do you get with work, in some places its only 2 weeks in the states compared to 5 here. This might impact on trips back home. So if you're thinking of working and your child is in childcare what will you do when they are ill. Be wary of relatives who have offered to babysit while you work, you see it all the time here where people move for this then the relatives can't cope or change their mind and they are completely stuck. Always have a back up plan
