我国内的同学婆婆找了个美国老头结婚了，先在正在办移民，据说已经差不多快了。 同学想知道这种情况下她老公和他可以通过她婆婆或者美国老头的关系移民美国吗？
-No. The marriage of your同学婆婆 and 美国老头 has to occur before your 同学老公 turned 18 years old so that 美国老头 can sponsor your 同学老公's green card.
同学和他老公先在还没有领证。如果可以的话大约要办多久呢？
是要等到她婆婆公民以后办好吗？
-Yes. 她婆婆 takes 3 years to become a US citizen after she gets the green card and then sponsor her hu*****and including her and kids (if any) which normally takes about 10 years (F3 category). 她婆婆 can not sponsor the green card before becoming a US citizen if her hu*****and marry her.
我一窍不通的，所以上来问问大家。
