If a person sleeps before Maghrib and does not wake up until after the dawn has appeared, is his fast valid?

Question : Yes.

Answer : If a person sleeps before the day in the month and does not wake up until after the dawn of the next day, the school of thought (madhhab) holds that his fast is not valid and it is like divorce, so the correct view is that it is valid and it is not like divorce. This is because every person, when Ramadan enters, intends to fast every day.
