My daughter visited me from September 4, 2016 to January 24, 2017. She is Australian, she didn't need a visa (Australians may stay 3 months without visa).
But she needed to stay a little bit more, because her baby was sick. The préfecture in Reunion gave her a one month stay permission.
Now she wants to come back to Reunion for some days (July 5th) and we want to fly together to France and then Germany (July 17th).
Is she allowed to come back to Reunion? Can she travel into the Schengen area on these dates? (Her baby is German, so for him is no problem.)
