From the DV instructions it saysHi all,
I've just recently renewed my passport and I was wondering if I need to update my DS-260? (since I applied with my old passport)
Does anyone know anyone who has gone through this before?
Thanks!
13. What if my passport expires, or I lose it before I apply for a visa?
If your passport number changes for any reason, you will have to provide evidence of why it has changed to the Department of State’s Kentucky Consular Center (KCC) before they will schedule your DV interview. If you enter a false, inaccurate, or invalid passport number on your DV entry, you will be ineligible for a DV. We suggest you make a legible photocopy of the passport you use for the entry and store it in a secure location with your entry confirmation number (FAQ #27). A photocopy alone is not proof you entered a valid passport number on your entry, but it can help you explain the situation. The final determination is made by the Consular Officer at the time of your DV interview.
So not 100% on the answer but guessing you either have to message KCC letting them know with an explanation + send a copy of it, or I've also heard you have to take your old expired one as well as your new valid one to your interview (definitely have to do this, not sure if you have to notify them beforehand). I guess it also depends if you're DQ'd yet or not, since if you aren't they might not make you DQ if your passport isn't valid?
Maybe someone else can give a better reply though.
