回复：thanks a lot, helpufill. But..

I am sorry, I really dont know. My hu*****and is in Army, so everything from him. Oh, I remember something. You need something from the one who supports you to apply the greencard. For example, in my case, I need my hu*****and's W2, not mine. Yes, i think you need I864, fill it out, then get your hu*****and sign it, that is it!:) Good luck.
