I go to the Enter Entrant Information form by following the link https://dvprogram.state.gov/ESC/CheckStatus.aspx and I fill in all the data correctly, but when I fill in the authentication code at the very bottom of the page to confirm that I am not a robot, I always get an error message that says: Please enter the code as you see or hear it. Please, tell me why this is possible if I filled in all the data correctly?
