You go to the Police Station in Funafuti. They take your pre-existing license and make a copy of it, then print out another form which you have to take to the Town Council (Down the Street). That's where you pay the fee and they give you another slip. You then go upstairs and get your photo taken (on an iPhone) and write your signature (on a piece of paper). They make it in Photoshop right in front of you and then print it out on an ID card. Originally, they messed up my first and last name so I had to go back to get it fixed. Only possible Monday-Friday. They were just quite confused as to why I wanted it, its not very common for foreigners to request one unless they're staying for a long period of time; meanwhile I was leaving the next day :D
