拜讀了皮匠老師的博客關於follow to join 一章。獲益匪淺。但就自身情況還有幾個問題不甚明了，還請諸位大俠賜教。
本人eb3排期11月即將排到，想盡快把國內的老婆孩子辦過來。可能有兩條路走：
方法1
老婆孩子國內遷B2（冒有移民傾向被拒的風險）。如闖關成功，在B2有效期內遞485。但問題來了。
A 是否遞了485後即可合法居留美國，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 如果老婆作為副申請人曾經遞過485，中途回國至今（未申請AP），請問舊的485是否對再次申請有影響？-No affect the second I-485 filing, but may affect B2 visa application (just try B2 visa, anyway).

-
C 老婆孩子應該分開遞還是一份485就能搞定？-Two I-485s for two people.
方法2 B2被拒，遞824申請follow to join
A 824是否一定要等主申請人綠卡到手後才可申請，-Yes
還是排期到了即可？-No.
B 老婆孩子應該分開遞還是一份824即可？-One is enough for your老婆孩子
C 如824批準後還要大約多長時間廣州領館才發簽證通知？-Normally 6 months to one year, case by case.
D B2被拒是否對去廣州簽證有影響？-Not affect it.
