想確認一下。假定男的已拿到綠卡，女友在國內，還未結婚。如果女友用B2來美，然後在美結婚，然後應該怎麽做才能讓女方長期留在美國？
-女方 can change B2 to F-1, H1 etc. which allow her to stay in US for several years.
比如說馬上給女方辦綠卡（第二類優先）。這種情況下，有沒有交了申請女方就能在美長期居留（不受B2期限約束）的說法？
-She can not stay with B2 for several years because USCIS probably will not approve the B2 extension again and again (B2 only can be extended for up to 6 months at one time).
Another choice is that the 女方 just stay in US illegally until the hu*****and get the US citizenship and then sponsor the wife green card.
我隻能想到這些。老師見多識廣，有什麽點子，請不吝賜教。
