Use the Information Below to Plan for APHA 2021

With the uncertainty around COVID-19, APHA is aiming to host a hybrid online/in-person meeting, and we're working on what that will look like. Check for more updates on the Annual Meeting landing page. Here is some helpful information for international visitors traveling to and from the United States.

Letters of Invitation

If you require a letter of invitation for visa purposes, you must:

  1. Register and submit payment for the Annual Meeting.
  2. Generate a letter of invitation using your registration ID from your confirmation letter.
    (If you have not registered but require a letter of invitation, please email APHA.)

Note: In the event that a visa application is denied, please provide documentation to APHA confirming the denial. APHA will refund the registration fees in full upon receipt of documentation.

U.S. Visa Information

A US visa allows a foreign citizen to travel to a United States port of entry and request admission into the U.S. from a U.S. Immigration Inspector. Since the terrorist attacks of Sept. 11, 2001, visa applications have been subject to a greater degree of scrutiny. The time frames for visa processing today are difficult to predict with accuracy for any individual applicant and could vary significantly by country. Advance planning by the traveler is essential to receive a visa in time for their visit to the United States. General information about obtaining a visa can be found on the U.S. Department of State website.

There are several steps to apply 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. It is best to check out your Embassy's website before you begin the process. You will need to schedule an interview at a U.S. Embassy or Consulate. Wait times for interview appointments vary, so plan ahead and come prepared with the proper documentation. Be aware that there is a non-refundable visa application fee. 

A step-by-step visa application process can be found on the U.S. Department of State website.

For the 38 countries in the Visa Waiver Program, citizens meeting the visa waiver criteria will not need a visa, but they must have a machine-readable passport and meet all visa waiver requirements.

Remember, plan early, do your research and be prepared. Understanding the process before you apply will help guarantee your success. For more detailed information about U.S. visas, visit
