International Invitation Letter

If you must apply for a temporary, non-immigrant visa to attend AIRP, you are advised to apply as soon as travel to the United States is contemplated and not later than three to four months in advance. Apply early!

AIRP offers an official letter of invitation for international attendees. Please contact Obse Debela at for more information. The visa letter of invitation, though not required for the visa application, can assist as a supporting document. Present this letter to the consular officer during the visa interview. This letter by no means guarantees admittance to the United States but can provide compelling evidence for immigration officials to consider. Please note that the AIRP cannot intervene with U.S. embassies abroad or with the U.S. State Department on behalf on any attendee.

Visa Waiver Program

The Visa Waiver Program (VWP) enables nationals of specific countries to travel to the United States without obtaining a visa for tourism or business stays of 90 days or less. For more information, see the United States Department of State's Visa Waiver Program information.

Travel Approval Required for Visa Waiver Countries

The Department of Homeland Security (DHS) Electronic System for Travel Authorization (ESTA) is a free, automated system used to determine the eligibility of visitors for travel to the United States under the VWP. A valid ESTA approval is required for all VWP travel to the United States. The electronic version collects the same information as the paper I-94W form also used for travel to the U.S.

ESTA applications may be submitted at any time prior to travel. An ESTA authorization generally will be valid for up to two years. Authorizations will be valid for multiple entries into the United States. The DHS recommends that travelers submit an ESTA application as soon as they begin making travel plans.

In 2010, the DHS transitioned to enforce compliance of the ESTA requirement for VWP travelers. Therefore, VWP travelers who have not obtained approval through ESTA should expect to be denied boarding on any air carrier bound for the United States.

Effective May 24, 2022, U.S. Customs and Border Protection will charge $21 for travelers intending to travel to the United States with an approved ESTA. The fees include a $4 administrative fee and a $17 travel promotion fee established by the Bipartisan Budget Act of 2018. More information regarding this fee can be found on the Customs and Border Protection website.

Tips for Successful Visa Applications

Include a letter of invitation from the meeting organizer. Please contact Obse Debela at for more information.

When possible, provide proof of professional scientific and/or educational status, society membership and/or meeting registration.

Visa applicants are expected to provide evidence that they intend to return to their country of residence. Therefore, applicants should provide proof of binding or sufficient ties to their home country or permanent residence abroad. Visa applications are more likely to be successful if done in the visitor's home country.

Applicants should present their entire trip itinerary, including travel to any countries other than the United States, at the time of their visa application.

All applicants must be able to qualify for a visa on their own merits under the requirements of the Immigration and Nationality Act.

Late Registration Policy

Any registration received less than 30 days prior to the start of the four-week course for (MIT) will be charged a $300 late fee in addition to the regular course fee.

Program Registration: is not complete until payment has been fully processed. Payments must be received within 45 days of the date of registration. Any slot not paid within 45 days of registration will be canceled.

Acceptable Use of Score Data Policy

ACR Acceptable Use of Exam Data Policy - Examinations & Assessments

  1. BACKGROUND. ACR develops, administers, and scores various examinations and assessment tests, as part of its educational mission. These instruments include those used to assess educational progress, such as the diagnostic radiology (DXIT™) and radiation oncology (TXIT™) in-training examinations; and those used to assess course participation and completion knowledge, such as those included during or at the conclusion of various on-line and in person courses. As such, it becomes important to articulate how examination related data can and should be used, especially considering requests from outside parties for examination related score data. The intent is to provide guidance for staff, committees, etc., concerning the acceptable use of examination data in fulfilling their duties.
  2. TYPES OF EXAMINATION/ASSESSMENT DATA. In the context of occupational and educational testing, there are three general types of data that result from the ongoing administration of examinations and assessments:
    • Score Data. This data includes raw, percent, percentile rank and/or scaled score information for individuals, institutions, or test populations.
    • Status Data. This typically takes the form of passing and failing rates among a particular testing population for a given assessment or test.
    • Psychometric Data. This includes various kinds of statistical information which is calculated to determine how an examination instrument is performing, and how each item comprising that instrument is performing. The primary purpose of this information is to ensure that a particular instrument is measuring the cognitive traits (or knowledge, skills and abilities) it is intended to measure, and is usually gathered into an Item Analysis Report containing a summary of test statistics, a test frequency distribution, an item quintile table, and item statistics.
    • Score Data. For ACR norm referenced examinations (i.e. educational tests), such as the in-training examinations, institutional and population score data will be provided to residency Program Directors for the purpose of assessing individual resident progress and for self-evaluation of the Institution’s educational programs. This data shall also be made available, upon request, by such ACR committees or bodies tasked with the development and administration of the examination for the sole purpose of performing their tasked mandates and for ensuring the quality of the examinations. Additionally, Program Directors will be encouraged to share individual score data with residents.

      For course participation and completion assessments, score data shall be made available, upon request, by such ACR committees or bodies tasked with the development and administration of the courses in question for the sole purpose of performing their tasked mandates and for ensuring the quality of the courses or educational activities.

      Due to the significant potential for the misuse or misinterpretation of test score data, it shall not be provided for any other purposes or entities than those described above.
    • Status Data. For ACR competency examinations, pass/fail status data shall be provided solely to individual test takers. Additionally, failing candidates shall be provided diagnostic data to give the test taker information that can be used to help the test taker remediate performance and to guide future study plans.

      Additionally, status data shall also be made available, upon request, by such ACR committees or bodies tasked with the development and administration of the examination for the sole purpose of performing their tasked mandates and for ensuring the quality of the examinations or assessments.

      In general, pass/fail data or rates will not be published or made publicly available by ACR, except for specific educational or similar purpose deemed to be appropriate by the appropriate governing committee.
    • Psychometric Data. Psychometric data is created as part of the ongoing assessment of how ACR examinations are performing and to ensure ACR testing instruments meet testing industry standards appropriate for the type of instrument in question. Accordingly, psychometric data shall be made only available, upon request, by such ACR committees or bodies tasked with the development and administration of the examination for the sole purpose of performing their tasked mandates and for ensuring the quality of the examinations or assessments.

      For reasons of test security, and due to the significant potential for the misuse or misinterpretation of these types of measurement statistical characteristics, psychometric data will not be published or made publicly available by ACR.

Radiologic-Pathologic Categorical Courses

Categorical courses enable participants to utilize knowledge of how radiology and pathology correlate to improve their diagnostic accuracy in identifying specific diseases, their treatment and potential complications.
