Is it possible to change consulate if I don't get an appointment?

[Ashish Gandhe]

I'm filling my DS-160 with Vancouver as the Consulate. However,  if I dont manage to find an appointment soon enough in Vancouver, is it possible to change the consulate in the original DS-160? If not, do I have to create a new DS-160? In that case, does the old one need to be link or simply ignored?

After you submit DS-160 i don't think it will allow you to change the consulate, so to be safe side and avoid delays, fill up a new DS-160 with the consulate that has appointments available.

Just starting filling multiple DS 160. You just need AAXX number. Once you confirm and get appointment finish only the DS 160 that you need for that location and submit it and you will get confirmation page. The remaining DS 160s you can just leave them and they will be removed after sometime.
