請問大家，目前母親作為主sponsor給弟弟辦理的移民申請，去年十月已經收到DOCUMENTARILY QUALIFIED電子郵件，等到現在沒有進一步的消息，請問DOCUMENTARILY QUALIFIED之後下一步就是麵試嗎？一般多久會安排麵試？體檢又該什麽時候做？需要做什麽準備嗎？
-Wait for NVC to contact your mother. NVC will send your mother the appointment notice and instructions for the interview including physical exam requirements.
另外母親在美國的地址發生變動，需要聯係NVC嗎？是不是所有的通知都會通過電子郵件發送，不需要郵寄地址？現在NVC不提供電話服務，大家怎麽聯係NVC,有沒有NVC辦公室可以去預約谘一些問題？擔心會不會有紙質通知被寄到舊的地址，導致我們沒有收到通知。
謝謝！
-Your mother need to inform NVC about her address change. I cited the following at this link:
How do I update my mailing address or phone number?
To update the mailing address or phone number of anyone associated with a case, please contact NVC using our Public Inquiry Form. Remember that whenever you contact NVC please provide your case number, the name of the petitioner, and the name and date of birth of the principal visa applicant.
