Hi, yes they will contact all the referees you have listed on the filling form.
But only for the 5 past years.
The already sent all the letters to the referees because i had only two referees who i am still friend with and they called to tell me they have received a fiiling form from ANA.
Do you know how many you were to successful on the 18th?
For the 19th we were 3 to successful.
