"cuando regresas" o "cuando regreses"

Question

Which phrase is correct, "cuando regresas" o "cuando regreses"?

Answer 1

Are you asking when are you coming back?

In that case, it is ¿Cuándo regresas?

If it's an statement, for example, I'll be here when you come back, then it is "Voy a estar aquí cuando regreses".
