Dropbox appointment for h1b h4 EAD location

Hi, quick question.
We live currently in USA, I am a h1b holder from Mumbai(place of residence)
My wife is h4 EAD visa holder and she is from Chennai. We are planning to travel to India and we are eligible for Dropbox. Is it ok if I get my Dropbox appointment in Chennai, as I see dates available. Or should we have a Dropbox appointment in Mumbai(my place where I got my h1b) earlier.

You can apply wherever you want, no issues.
