REply

十几年前我给妹妹一家办了移民申请。Priority date is April 15, 2007. 当几年前她的Priority date 在Chart B到期时，她并不很想继续办理，所以一直拖着。

现在她们一家终于决定办理移民。In July 2023's Visa Bulletin, the date in Chart A （Final Action) became April 22, 2007. In other words, her priority date is now earlier than the date in Chart A (final action).  

我的问题是：

1. 现在才开始办（next step is "step 3 Pay Fees"), 还来得及吗？ 是不是必须在一年内 （i.e., by July 2024) 她必须得到签证Approval (或 完成 Step 11 applicant interview)?  

-Did NVC ask you to submit the documents before when the prority date was current based on B Form a few years ago? If yes, you need to contact NVC to see whether the case is still open at NVC. If yes, then you can continue to submit the documents and pay the fee.

2. Are there any deadlines for her based on her priority date?

-Yes. You need to provide the documents and pay the fee within one year from the date NVC ask you to do it. That is why I suggest you to contact NVC to see whether the case is still open there because NVC asked you to do it a few years ago.
