Some websites offer to complete ESTA applications for a fee, often many times more than the required fee charged by the U.S. government. Access and application through the official U.S. government website are available to any travelers who qualify under the VWP program. Prevention of such "ESTA fee scams" was made more difficult when the mandatory U.S. government fee was imposed, as previous public education efforts focused on getting out the message that ESTA applications were free of charge and anybody requesting payment was an unauthorized third-party.[18] Third-party websites try to make themselves look legitimate by using official-sounding web addresses and posting logos that resemble the U.S. government emblem.
