International Megan's Law of 2011

Requires the U.S. diplomatic or consular mission in each foreign country to establish and maintain a countrywide nonpublic sex offender registry for sex offenders who are U.S. citizens or permanent residents who remain in such foreign country for more than 30 consecutive days or more than 30 days in a 6-month period. Requires such a sex offender to register with such mission and to appear at the mission every six months to verify information in the registry. Requires the mission to forward new information about a sex offender to the Attorney General for purposes of updating the National Sex Offender Registry and keeping domestic law enforcement informed. Requires the Attorney General to transmit such information to the state of the legal or last known residence of such sex offender.

Grants federal, state, local, tribal, and territorial law enforcement agencies access to all information in a sex offender registry maintained by a mission. Denies access by the general public to such information but permits access for certain entities that provide direct services to minor, official law enforcement entities, or entities affiliated with an official law enforcement agency for the purpose of investigating a possible sex offense.

Requires a mission that determines that a sex offender has failed to comply with registration and reporting requirements to notify the Attorney General and revise its registry to reflect such failure. Amends the Sex Offender Registration and Notification Act to provide for the assistance of federal law enforcement agencies in apprehending sex offenders who violate registration requirements.

Directs the President to establish the Center to monitor the travel of high interest registered sex offenders and to notify countries to which such sex offenders are traveling. Requires the Center to: (1) consult with the National Center for Missing and Exploited Children, ECPAT-USA, Inc., World Vision, and other nongovernmental organizations regarding the international travel of registered sex offenders; (2) issue the Center Sex Offender Travel Guidelines for the assessment of whether sex offenders who report international travel are considered high interest registered sex offenders by U.S. law enforcement; and (3) provide written confirmation to a sex offender of the receipt of a travel report within seven days before the date of departure indicated in the report.

Authorizes the Secretary of State to revoke the passport or passport card of a convicted sex offender and limit to one year the validity of a passport issued to an individual designated as a high interest sex offender.

Expresses the sense of Congress that the President should: (1) strongly encourage foreign countries that have an age of consent to sexual activity below the age of 16 to raise that age to at least 16 and foreign countries that do not criminalize the appearance of persons below the age of 18 in pornography to prohibit such activity; and (2) formally request foreign governments to notify the United States when a U.S. citizen has been arrested, convicted, or sentenced, or has completed a prison sentence, for a sex offense against a minor in the foreign country.

Amends the Trafficking Victims Protection Act of 2000 to expand criteria for the elimination of severe forms of trafficking in persons by providing for international cooperation in the reporting of foreign nationals who are suspected of engaging in severe forms of trafficking of persons in another country.

Encourages the President to use authorities under the Foreign Assistance Act of 1961 to assist foreign countries in identifying sex offenders and providing and receiving notification of child sex offender international travel.

Requires the Inspectors General of the Departments of Justice and State to audit and report on the implementation of requirements for sex offender travel and foreign registration, the International Sex Offender Travel Center, and travel guidelines issued by the Center.
