Staying for 6 months from UK to US

[immihelp]

I am in the United Kingdom and have a UK passport. I am planning on going to the USA to visit some friends. Do I need to get a visa. additionally, I would like to stay 6 months or longer. How should I go about doing this. Do I have to do this in the UK?

If you would like to stay for 90 days or less, you don't need visa. Read http://www.immihelp.com/visa-waiver-program/

For 6 months stay, you need visa. Read http://www.immihelp.com/visitor-visa/

If I come into the country without a visa, is there a way to extend my stay without having to leave the country?
