• Non-US citizens may need a visa to enter the US.
  It is your sole responsibility to ensure that you are eligible to enter the USA for the conference. If needed, an invitation letter for a US visa application will be provided for conference delegates after conference registration and payment. Delegates are required to indicate on their registration form that they will need an invitation letter for their US visa application.
• Plan ahead - apply for you visa early.
  Depending on your country and citizenship, visa processing may take several weeks. If you need a visa, register for the conference as early as possible and pay your conference fees along with your registration so we can send you the invitation letter. We will not accept any visa delays or denied visa as an excuse for no-shows!
