Nursing in USA

Hi,

I'm a registered Adult Nurse in the Uk with a honors degree in acute care, a post graduate certificate in critical care and a mentorship qualification. Since qualifying 6 years ago I have worked on an acute medical ward for 10 months, Adult Cardiothoracic Critical Care for 5 years and since May this year I have been working at a well known Children's Hospital here in London in Cardiac Critical Care holding a senior staff nurse post (band 6).

My question really is does anyone have any information about working in New York, which exams would I need to sit and how would I go about getting a visa? Do I get a sponser or something? Is it best to go through an agency? Also what is the name of the post I can expect to apply for (as looking online they seem to be called different things). And what is the job climate and pay like there for nurses?

This is all very early days so any information/ advice would be greatly appreciated.

Thanks
