how do I move to the USA?

[sentviaemail]

Hello, I'm an Italian student of 18 years old and I would like to move and
work in the USA in about a year.
Do I need green card for this?
How can I get the green card?
Is there a cost for it?
Do I need other documents?
How long is going to be valid?
What is the green card lottery?
Are there any advantages or disadvantages in the US for me as Italian?
Thanks for your help. Best regards
