感謝8老師上次對我問題的詳細解答，為我指明了方向，拜謝！
這次還有幾個問題請教：
1. EB1 2018年6月中國大陸出生的表A仍然不current，但表B current，但合時才能知道每個月表b是否啟用呢？（至少從6月的bullentin中看不到是否啟用表b的信息）。如果啟用了表b是不是意味著就可以遞交485了？
-No. Normally B Form is set up mainly for the people to submit the documents for apply for the immigrant visa outside US though sometimes it is also used for I-485 filing. So, you need to check this website each month to see whether you can file I-485:
https://www.uscis.gov/visabulletininfo
2. 如果需要等到10月的新財年，是不是也要最早9月底把材料寄出，以保證移民局蓋戳的時間在10月1日當天或以後？如果寄早了會有麻煩吧？
-Correct.
是以郵件送達的日期為準嗎？-Arrival date.
3. 如果申請人在美國，但因為其他原因（為了工作簽證到期後可以回國一邊工作一邊等visa的靈活性）選擇走consular processing是否也可以？
-Yes.
留美國的地址給NVC進行聯係是否沒問題，隻是等收到麵試通知回國體檢+麵試就可以對吧？
-You had better change your address to your friend's address in US so that your friend can receive the USCIS/NVC letters for you. You also assign your friend as your agent when NVC ask you to idenfity an agent in the future. Thus, your friend will receive all of the NVC letters for you.
依您看現在CP和485相比總體等待時間哪個長？-Hard to say.
另外如果走CP的話，整個過程中需要主申請人的140批件和petition letter嗎？（雇主不realease 140材料，隻有140 number）
-Your employer needs to file I-824 to ask USCIS to forward your I-140 to NVC for processing your immigrant visa application. So, talk to your employer or lawyer.
萬分感謝8老師長久以來無私的幫助。
