十幾年前我給妹妹一家辦了移民申請。Priority date is April 15, 2007. 當幾年前她的Priority date 在Chart B到期時，她並不很想繼續辦理，所以一直拖著。
現在她們一家終於決定辦理移民。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).
我的問題是：
1. 現在才開始辦（next step is "step 3 Pay Fees"), 還來得及嗎？ 是不是必須在一年內 （i.e., by July 2024) 她必須得到簽證Approval (或 完成 Step 11 applicant interview)?
2. Are there any deadlines for her based on her priority date?
謝謝！
