Before traveling to the U.S., a citizen of a foreign country must generally obtain a nonimmigrant visa for temporary stay. Should you require information on obtaining a visa, please visit: http://travel.state.gov/content/visas/en.html.  This web site will answer all your visa questions and help you in obtaining the correct type of visa for your visit. 

Should you require a formal invitation for Visa application purposes, please send your request to kathleen@ballos.com. 

Include the following information with your request:

• Full name
• Date of birth
• Passport number
• Address
• Paper ID and title of your paper, if you are a presenting author

Note: International authors whose papers are accepted to ICAD 2025 but cannot make it to the US to participate in-person on June 24, 2025 may be able to present virtually.  This will be determined on a case-by-case basis.
