British Expatriate Network

Hi, I know this has been covered before, but does anyone have an updated view. I am already working in the USA .....does this make it easier to apply for a green card, if so how long before I can apply or does my employer have to do all the filing. Already feel that I owe them so much now I'm afraid to ask for help with a green card.
Thanks

i'm watching this with interest as we will be applying for a green card as soon as we move over (hopefully october)
