我們是第一種情況。
1。今天剛剛收到郵件說通過，我可以聯係USCIS不要transfer 到NVC嗎？
--Probably no, but you can try it.
如果可以，過一年後想再transfer是不是就不行了，隻能在境內申請？
-If USCIS accept your request not to transferring your case to NVC and your parents want to apply for the immigrant visa later, then you need to file I-824 to ask USCIS to transfer your approved I-130 to NVC later. Or your parents come to US to file I-485 (the problem is that they may not be allowed to enter US using B2 visa due to immigrant intent in this case).
2。如果我在第一年結束前和NVC聯係要求保留I-130可以嗎？
-Within one year after NVC contact you, you may pay the fee, or submit some required documents, or use the Public Inquiry Form to update information like addresses to resets the one-year clock.
NVC will send you a notice before they termiante your I-130. If you receive such a notice, you can request NVC to keep your case active/open by giving the reasons.
3。 您說第一年內必須遞交 DS-260，那是不是隻要交了DS-260就可以保住I-130了，如果其他例如 Affidavit of Support, and required civil documents 過了一年後交，是不是沒有關係，還是說所有相關材料都要在一年內交齊？
-Not have to submit all the documents at one time.
4。如果第一年被terminated, 第二年reinstate肯定沒有問題嗎？需要給出特殊理由嗎？
-If your case is terminated by NVC, you can request reinstatement within one year by explaining you did not take the action due to circumstances beyond your control.
5. 如果轉回到USCIS，以後任何時候想在境內申請都可以用這個I-130，沒有時間限製，對嗎？
-Correct unless USCIS revoke your I-130 due to some kind of reasons such as fraud.
