下個月NIW的PD current, 但是準備今年回國工作一段時間，請教下8老師下麵幾個問題：
1）去年10月提交了I824申請AOS轉成CP，如果直接回國的話是不是等到I824被批準後等NVC通知去廣州使館簽證就可以了？
-Yes.
這樣拿綠卡的風險比等在美國AOS大嗎？到時候還需要先拿到offer letter才能移民簽證嗎？我的140是NIW
-Technically you don't have ot have a job offer, but practically you had better have a job offer from a US employer when you are scheduled for the interview and thus, it will be much easier for you to get the immigrant visa.
2）如果按照上麵CP操作的話，會不會總的流程比AOS要慢個6個月左右？現在I824好像批的很慢。有沒有辦法拿著I824的receipt number和批準的I140聯係NVC要visa number的呢？還是非要等I824批準？
-Your I-824 must be approved first, then USCIS can forward your case to NVC for processing for the visa application. It takes much longer time than you file I-485 within US to get the green card.
3）如果在美國等綠卡的話，是不是等到拿到AP就可以邊回國邊工作邊等綠卡了？
-Yes you can, but USCIS may ask your employment status within US (see above answer).
我現在是H1B，如果回國的話H1B就失效了，這會有影響嗎？
-No.
還是非要等到綠卡正式拿到才能回國？
