I am an US citizen interested in moving and working in the UK.

I have some questions:

What differences in culture should I as an American should be aware of before moving into the UK?

What is the tax rate? Where is the lowest cost of living in the UK? What location has the best rate for employment and job growth?

Taxes, how does it work if temporarily working in the UK, both in paying the UK and US governments?

Any advice on how to look for a job in the UK while living here in the US?

What obstacles (if any) would I have if I decided to send/wire money home?

What steps should I take in order to gain a work permit and be able to work in the UK legally?

What jobs should I look for as an unskilled laborer?
I currently work as security and wondering if an US citizen can gain the necessary permits needed to work security in the UK while not being a citizen of the UK. If not, what other jobs should I look for in the UK?

I know I asked a lot of questions however please answer what you can and I look forward to hearing from you.

Thank you and have a good day.
