Visa Application Information

What do I need to do to attend the 2025 NAHB International Builders’ Show from a foreign country?

Depending on your citizenship, you may need a visa to travel to the United States to attend the International Builders' Show.

Read the information below to find out more about whether you need a visa and how to obtain one.

Complete visa information can be found via the U.S. Department of State's Bureau of Consular Affairs.

Visa Waiver Program

The U.S. government's Visa Waiver Program enables eligible citizens of specific countries to enter the United States for tourism or business for a period of 90 days or less without obtaining a visa..

Learn more about which countries participate in the Visa Waiver Program.

Electronic System for Travel Authorization (ESTA)

A valid ESTA approval is required for all Visa Waiver Program (VWP) participants to travel to the United States. ESTA applications may be completed online at the official DHS website.

The Department of Homeland Security Electronic System for Travel Authorization (ESTA) is used to determine the eligibility of visitors to travel to the United States under the VWP. It collects the same information as the paper I-94W form that VWP travelers fill out en route to the United States. ESTA applications may be submitted at any time prior to travel. An ESTA authorization generally will be valid for up to two years. Authorizations are valid for multiple entries into the United States. DHS recommends that travelers submit an ESTA application as soon as they begin making travel plans.

Visitors seeking to travel to the United States under the VWP are subject to enhanced security requirements and will be required to pay an administrative fee. All eligible travelers who wish to travel to the U.S. under the Visa Waiver Program must apply for authorization and then pay the fee.

VWP travelers who have not obtained approval through ESTA should expect to be denied boarding on any air carrier bound for the United States.

Learn more about ESTA on the DHS Customs and Border Protection (CBP) website, www.cbp.gov.

Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a non-immigrant visa for a temporary stay or an immigrant visa for permanent residence.

If you are not eligible for the Visa Waiver Program and need a visa to attend the 2025 NAHB International Builders’ Show, you can now complete the visa application form online.

Visitor visas are non-immigrant visas for people who want to enter the United States temporarily for business (visa category B-1), tourism, pleasure or visiting (visa category B-2), or a combination of both purposes (B-1/B-2). A Business Visitor Visa (B-1) (PDF) should be appropriate for a conference, meeting, trade show or business event attendees, or trade show employees of foreign exhibitors at international fairs (excluding government representatives).*

How to Apply

There are several steps to applying for a visa. The order of these steps and how you complete them may vary at the U.S. Embassy or Consulate where you apply.

Please consult the instructions available on the U.S. Embassy or Consulate website where you will apply.

Complete the Online Visa Application

Online Nonimmigrant Visa Application, Form DS-160

  1. Learn more about completing the DS-160 – You must: 1) complete the online visa application and 2) print the application form confirmation page to bring to your interview.

  2. Photo – You will upload your photo while completing the online Form DS-160. Your photo must be in the format explained in the Photograph Requirements.

Schedule an Interview

While interviews are generally not required for applicants of certain ages outlined below, consular officers have the discretion to require an interview of any applicant, regardless of age.

If you are age:

  • 13 and younger, then an interview is generally not required.
  • 14-79, then an interview is required (some exceptions for renewals).
  • 80 and older, then an interview is generally not required.

You must schedule an appointment for your visa interview, generally, at the U.S. Embassy or Consulate in the country where you live. You may schedule your interview at any U.S. Embassy or Consulate, but be aware that it may be difficult to qualify for a visa outside of your place of permanent residence.

Wait times for interview appointments vary by location, season and visa category, so you should apply for your visa early.
