拜读了皮匠老师的博客关于follow to join 一章。获益匪浅。但就自身情况还有几个问题不甚明了，还请诸位大侠赐教。
本人eb3排期11月即将排到，想尽快把国内的老婆孩子办过来。可能有两条路走：
方法1
老婆孩子国内迁B2（冒有移民倾向被拒的风险）。如闯关成功，在B2有效期内递485。但问题来了。
A 是否递了485后即可合法居留美国，即不用延期B2？
-Yes, but they had better file their I-485s about 3 months later after they enter US using B2 visa in case USCIS think they have immigration intent before they enter US with B2 visa.
B B 如果老婆作为副申请人曾经递过485，中途回国至今（未申请AP），请问旧的485是否对再次申请有影响？-No affect the second I-485 filing, but may affect B2 visa application (just try B2 visa, anyway).

-
C 老婆孩子应该分开递还是一份485就能搞定？-Two I-485s for two people.
方法2 B2被拒，递824申请follow to join
A 824是否一定要等主申请人绿卡到手后才可申请，-Yes
还是排期到了即可？-No.
B 老婆孩子应该分开递还是一份824即可？-One is enough for your老婆孩子
C 如824批准后还要大约多长时间广州领馆才发签证通知？-Normally 6 months to one year, case by case.
D B2被拒是否对去广州签证有影响？-Not affect it.
