DS-160 created for Chennai , IW appointment at Delhi

Hi

When I filled in the DS-160, I had selected Chennai as the VISA location, I was eligible for IW, but when I went to schedule OFC appointment, I could not find a date in Chennai for my timeframe.

So I selected Delhi VAC ,it showed OFC appointments for my date in Delhi and drop box location, so I selected one of them.

Will this be an issue? Will they ask me to go back to chennai for OFC and dropbox ?

You can select whatever consulate you like, no issues.
