How long will the NVC case be concluded and there will be an interview notice?

It usually takes about 2 months from receiving the conclusion letter from NVC to receiving the interview letter.

It may take a year or even years for immigrant visa categories that have a schedule but have not yet arrived.

No matter whether it is the first immigration interview or the immigration re-signing interview, even if you don't need to update the DS-260 form information, you must log in to the CEAC system before the interview to ensure that your DS-260 form is in a "completed" state, not a "reopened" state. If the status is Reopen, remember to resubmit the form.
