American F4 immigrants sent the ds-230 form. When can I receive the interview notice?

If you send all the information, it usually takes about three months (sometimes longer) for the National Visa Center to transfer the documents to the consulate, and then the consulate will issue an interview notice. If you need supplementary materials, the National Visa Center will issue a supplementary notice, and the documents will be transferred to the consulate only after you have supplemented them completely.
