First off it may help if you do a little more reading of these forums on this subject and you will find a lot of advice with regards to the question that you are asking.
Not wanting to burst your bubble but it is not as simple as just deciding you would like to come and work in the USA.
Take it from someone who has gone through the process. I am a Brit who has been in the US for almost 25 years. I am here purely through marriage. If it wasn't for my wife there is no way I would have obtained a work permit.
To work and reside in the US you will either need a work permit or a Green Card. The work permits are for specialized professions for which the US cannot fulfill positions with American talent alone. Aviation does not qualify on this basis. Trust me I tried. The Green Card is not easy to get. It took me over 3 years after I was married to finally get a permanent card.
More importantly based on your experience and flying hours you are extremely low time. Again sorry for the bitter truth but there are many many US pilots with several thousands of hours more experience than you looking for work.
My advice is to stay where you are and build your time and don't think that there is some easy path to aviation glory just by moving to the land of milk and honey.
The rugby is better in New Zealand anyway!
Good luck and all the best for the future.
