i can’t find out where can i apply to became ATC.
In what country would you like to become an ATCO? Are you a member of that Division and VACC?
Welcome to VATSIM, Daria!
To become a controller, first choose the vACC/country you want to control in. Find their website and read the information for new controllers. A simple google search for “VATSIM [country]” will usually suffice. Each vACC and division has its own process and waiting list. The waiting times may vary, depending on popularity and training capacity.
