回复：回复：thank you

thank you so much for your reply. I read through the instruction of I-485, and it seems like you must file i-864 to get I-485 approved.
I talked to a lawyer one year ago, and she suggests
it is ok if you have no sufficient money to sponse you as long as you have enough before the interview. that is almost same as you just told me.
anyone else has ideas? has anyone file I-485 without I-486 before?
