All international travelers are responsible for ensuring they meet U.S. entry requirements prior to travel. Requirements vary by country of citizenship, but generally include the following:
1. Valid Passport
Your passport must be valid for at least six months beyond your planned departure date from the United States (some countries are exempt, but this is the safest standard).
Passports must be in good condition with at least one blank page.
2. Appropriate U.S. Travel Authorization
Most travelers will need one of the following:
ESTA (Visa Waiver Program)
Citizens of Visa Waiver Program countries may apply for ESTA authorization online prior to travel. ESTA approval is required before boarding a flight to the U.S.
B-1/B-2 Visitor Visa
Travelers who are not eligible for ESTA must apply for a B-1 (Business Visitor) or B-2 (Tourism) visa through the U.S. Department of State.
This process includes completing an application, paying a fee, and attending a visa interview at a U.S. embassy or consulate.
Visa processing times vary significantly by country, so international travelers are strongly encouraged to apply as early as possible.
3. Proof of Travel Plans
Upon entry, travelers may be asked to show:
- Proof of return or onward travel
- Confirmation of accommodations
- Evidence of sufficient funds for the duration of the stay
4. Travel Insurance (Required)
Because international travel policies and conditions can change, comprehensive travel insurance is required for all international tour participants.
Travel insurance should include:
- Trip cancellation and interruption coverage
- Medical and emergency evacuation coverage
- Optional “Cancel For Any Reason (CFAR)” coverage for maximum flexibility
- Insurance is particularly important to cover non-refundable expenses if travel must be canceled due to visa delays, personal circumstances, or changes in U.S. or international travel policies.
Important Refund Policy Notice
The International Plant Production Society (IPPS) cannot issue full refunds for tour cancellations once payments have been made and commitments to hotels, transportation, and venues are in place.
For this reason:
Travel insurance is required and is the sole means of protecting participants against financial loss due to cancellation.
Participants are responsible for selecting and purchasing a policy that meets their individual needs and risk tolerance.
