我持绿卡，如与大陆一女士结婚，她的签证排期大约要多长时间？
-about 5 to 6 months.
她的未婚子女可以同时申请来美吗？
-Yes if the child is less than 18 years old when you get married.
申请递件是给当地的领事馆吗？
-You need to file the I-130 following the I-130 instructions and then, wait for the National Visa center to contact you and send you the instructions and then, you just follow the NVC instructions to do what they request.
谢谢！
