我老公在美国递824表, 已批准, 824approval notice 上写
The above application has been approved. We have notified the consulate lisled above that the applicant's status has been adjusted to that of a lawful permanent resident
我们还要等nvc的通知吗?
-Your spouse needs to contact NVC to see whether the case has been received by NVC. If no, he needs to contact USCIS and ask USCIS to send it to NVC as soon as possisble. If yes, just wait for NVC to contact your husband. Please note that if USCIS does not send the I-824 to NVC, then you can not apply for the immigrant visa outside US.
Here is the similar case I helped someone (read all my responses in the follow-up questions):
