Resources for International Visitors

AmericanHort welcomes visitors from all around the world to Cultivate each year. Below are resources AmericanHort has compiled to help make your experience as convenient as possible.


  • Electronic System for Travel Authorization (ESTA)
  • Apply for Your Visa Early
  • Visa Application Interviews
  • Request a Letter of Invitation from AmericanHort
  • All nationals or citizens of Visa Waiver Program (VWP) countries who plan to travel to the United States for temporary business or pleasure will require, as of January 12, 2009, an approved ESTA prior to boarding a carrier to travel by air or sea to the United States under the VWP.

    An approved ESTA travel authorization is:

    Valid for up to two years or until the traveler’s passport expires, whichever comes first;

    Valid for multiple entries into the U.S.;

    Not a guarantee of admissibility to the United States at a port of entry. ESTA approval only authorizes a traveler to board a carrier for travel to the U.S. under the VWP. In all cases, Customs and Border Protection officers make admissibility determinations at our ports of entry.

  • Advance travel planning and early visa application are important since visa applications are subject to a greater degree of scrutiny than in the past.

    Applying for a visa can be a lengthy process. We recommend that you start early. Begin the application process four to five months before Cultivate. AmericanHort recommends that you secure your travel visa before registering for Cultivate.
