Relatives should emigrate. How soon can I receive package No.3 after receiving the confirmation letter?

In another month or two, you will receive the payment notice and living security from the National Visa Center. After one or two months, inform me to submit a copy of the first page of my passport, notarization of birth, notarization of marriage/divorce/notarization of death (if applicable), notarization of innocence, DS-230 form, parcel No.3 and two 2X2 visa photos.

Be conservative, and I'll inform you of your visa for questioning within six months! Good luck!
