想确认一下。假定男的已拿到绿卡，女友在国内，还未结婚。如果女友用B2来美，然后在美结婚，然后应该怎么做才能让女方长期留在美国？
-女方 can change B2 to F-1, H1 etc. which allow her to stay in US for several years.
比如说马上给女方办绿卡（第二类优先）。这种情况下，有没有交了申请女方就能在美长期居留（不受B2期限约束）的说法？
-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.
我只能想到这些。老师见多识广，有什么点子，请不吝赐教。
