I HAVE 6 ITALIAN TECHNICIANS IN ITALY WITH A LETTER OF INVITATION FROM THE MINISTRY. THEY WANT TO LEAVE ON THE 18TH BUT IN ROME WE DO NOT  HAVE TIME AND PLACE FOR THE APPOINTMENTS. THEY WILL STAY A COUPLE OF DAYS IN ACCRA FROM THE 16TH TILL THE 18TH...CAN THEY OBTAIN FOR THE VISA THERE? OR EVEN IN THE AIRPORT?THANK YOU.
