Walker said that she started by asking the Sri Lankan embassy whether they still had rights over the name Ceylon and, finding they did not, went on to ask the U.S. State Department whether producing a passport in that name would be legal, and they "couldn't show (her) it wasn't". Walker went on to produce hundreds of passports in different country names, trading as International Documents Service, and described her "finest hour" as being during the Iraqi invasion of Kuwait when a group of European oil executives were able to use her documents to pass through Iraqi checkpoints and escape to Jordan.
