我母亲去年12月底旅游来美，我替她申请绿卡，4月份递交申请，5月份打了指模，今天收到 I 765 Appliction for Employment Authorization 已经 approved 的通知。
请问：1. 是否需要拿这张表去办理SSN ?
-No. Need to provide the EAD for it.
2. 正常情况下多久能拿到绿卡？
-Case by case.
母亲急着想回去做身体检查。 谢谢！
-She may apply for advance parole to travel before she gets the green card. If it is urgent, she may apply for an emergency AP at the local USCIS Office. But don't miss the interview if any.
