If I go to graduate school in the UK what are my job prospects in the US?

I was accepted to study in the UK for graduate school in social policy but would like to return to the US to work after completion of the masters program. How valued is a masters from the UK in the US, and what are my chances of getting a good job in the US versus if i get a masters for the same program in the US?

I am not exactly sure but I can tell you that I have recently moved here from Canada and educated in Canada and my credentials have been well received. I think the job market in the US is open for "foreign" prepared employees

It depends on the quality of your degree and the contacts you know.
You can study anywhere in the world.
I think you'll be happy with it.

There are plenty of British people here in the USA who play-up their accent and modest credentials and go to the top.

You can be a plumber or a busboy in London, and make it to a six-figure job in the United States. You just need a little bit of skill.
