International Travel Support
Prohibited Direct Financial Support to Health Care Providers
Effective January 1, 2018, the MedTech Europe Code of Ethical Business Practice, AdvaMed, and APACMed prohibit medical device companies (MDCs) from providing direct financial sponsorship for registration, housing, travel, and meals to health care professionals (HCPs) to attend medical education conferences or training programs such as CTO Plus 2024.
Permissible Financial Support to Organizations
MDCs can give restricted educational grants to certain organizations to provide financial support to non-U.S.-based HCPs to attend CTO Plus 2024 and similar medical education events.
- Health care organizations: MDCs are permitted to provide educational grants to hospitals. A hospital administrator is responsible for allocating grants to eligible HCPs. Check with your cath lab director or hospital administrator for more information.
- National societies: MDCs are permitted to provide educational grants to national societies. Each society will be responsible for allocating grants to eligible HCPs. We encourage you to check with your society for more information.
- Trusted third-party organizations: CRF will provide the names of MedTech-compliant, trusted third-party organizations approved to seek educational grants from MDCs to provide financial support to eligible HCPs to attend medical meetings such as CTO Plus 2024.

Check Your Passport Before Booking Travel

If you need an entry visa, please visit your nearest U.S. Embassy or Consulate to obtain the necessary documents — and please plan in advance to allow enough time for the visa to be processed. Visit the U.S. Department of State website for information on the visa application process.
Applications for visas have taken as long as 90 days to process and could take longer. You must contact your local consulate AS SOON AS POSSIBLE about the application process for entry into the United States if you are not a U.S. citizen or lawful permanent resident.
The following information is for initial reference only. Please visit the U.S. Department of State website and other official U.S. government websites (listed below) for the most current and accurate information for planning your travel to the United States.
Visa Waiver Program (VWP)
Most citizens or nationals of the countries participating in the Visa Waiver Program (VWP) are permitted to travel to the United States for business or tourism for stays of up to 90 days without a visa. Please check the relevant requirements with the U.S. State Department or the U.S. Department of Homeland Security.
To travel without a visa on the VWP, you must have authorization through the Electronic System for Travel Authorization (ESTA). U.S. Customs and Border Protection (CBP) strongly recommends that you check your ESTA status prior to making any travel reservations or traveling to the United States.
Exceptions To Visa Waiver Program (VWP)
Some citizens of VWP countries must apply for a visa to enter the United States using the regular appointment process at a U.S. Embassy or Consulate. This requirement falls under the Visa Waiver Program (VWP) Improvement and Terrorist Travel Prevention Act of 2015 and pertains to:
- Nationals of VWP countries who have traveled to or been present in North Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011.
