Visa information & OkIP Invitation Letter
The organizers of OkIP Conferences encourage you to familiarize yourself with Visa and travel requirements well before the conference.
Visa Waiver Program among Certain Countries
The Visa Waiver Program allows citizens of 38 participating countries to visit the United States without a visa for less than 90 days if they meet the program’s requirements. Travelers using the Visa Waiver Program must also have valid Electronic System for Travel Authorization (ESTA) approval before traveling. Information about the Visa Waiver Program, including a list of the 38 participating countries and program requirements, can be found on the US Department of State’s website.
Attending an OkIP Conference in the United States
OkIP cannot intervene with US Embassies or consulates abroad or with the US State Department on behalf of any committee member or attendee.

Visa Application Process
What type of Visa?
There are several steps for applying for a business visa (category B-1), allowing visitors to travel to the United States to attend a scientific conference. These steps include completing an online nonimmigrant visa application, scheduling and attending a visa interview, providing appropriate documentation, and paying a visa application fee and visa issuance fee, if applicable. Please visit the US Department of State’s website for complete information on applying for a visitor visa. Because the visa process involves multiple, time-consuming steps, you must apply for your Visa well before your OkIP conference date.
Set Up Your Visa Interview
Suppose you are not eligible to travel under the Visa Waiver Program. In that case, you may be required to appear at a US embassy or consulate for an in-person interview before visa approval. There may be long waits to schedule a consultation, so start the application process as early as possible.
Tips for Successful US Visa Applications
- Have a valid passport.
- You must complete an online nonimmigrant visa application (Form DS-160).
- Visa applicants are expected to provide evidence that they intend to return to their country of residence.
- Applicants should provide proof of “binding” ties to their residence abroad, such as documentation of the following: family ties in their home country or country of legal permanent residency, property ownership, bank accounts, employment contract, or statement from employer showing that position will continue after the visit to the United States.
- Visa applications are more likely to be successful in a visitor’s home country than in a third country.
- During their visa application, applicants should present their entire trip itinerary, including travel to any country other than the United States.
- Include specific and detailed explanations related to your purpose for travel. Example: Copy of your OkIP Letter of Invitation.
- Provide specifics on how the applicant will cover travel and local expenses.
- If completion of travel plans is contingent upon early approval of the visa application, specify this at the time of the application; and
- Provide proof of professional scientific or educational status (students should provide a university transcript).
- Provide proof of an existing relationship with your inviter, OkIP, or other US entities. Example: Copy of your OkIP Conference registration.
- Note: The proof of purchase of an airline ticket differs from an item the embassy requested to document your trip itinerary. No assurances regarding the issuance of visas can be given in advance, so the purchase of a non-refundable airline ticket should be made after a Visa has been issued and you own a passport.
