Dropbox question

Hi I have a small question. Example: If we get the dropbox appointment in HYD but if we’re dropping off the docs in CHN(as we need drop off anywhere) . Which location should be mentioned in the DS-160 confirmation page either HYD or CHN? Could you pls respond?

You book the appointment after you submit DS160. You can go to any dropbox location so no issues if it is different from one mentioned in DS160.
