True, but there are distinct advantages to registering a copyright in the U.S.:

• Registration establishes a public record of the copyright claim.
• Before an infringement suit may be filed in court, registration is necessary for works of U. S. origin.
• If made before or within 5 years of publication, registration will establish prima facie evidence in court of the validity of the copyright and of the facts stated in the certificate.
