１学生，配偶对应的是F２；
H１工作的，配偶对应 H４；
那绿卡的配偶呢？是不是配偶得有其它的签证类型（比如F１上学等），才能来美国？

-There is not a visa specific for green card holder's spouse. Your spouse may try B-2 visa, etc. if she just plans for short visit. If she plans to live US permanently, you may sponsor her to apply for the immigrant visa.

还有个问题，公民给兄弟姐妹移民，那兄弟姐妹的孩子有没有年龄限制，比如成年了就不能移过来？

-Yes. If CSPA age > 21, then the child will be age-out.

CSPA age = the child actual age when the I-130 priority date is current - the I-130 epdning dates.
