Visa and Travel Information

Here is some helpful information for international visitors traveling in and out of the United States.

Letters of Invitation

If you require a letter of invitation for visa purposes, you must first register and submit payment for the Annual Meeting.  Once you receive confirmation of your registration, you may generate a letter of invitation online using your registration ID. 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 September 11, visa applications have been subject to a greater degree of scrutiny than in the past. 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. Citizens of Canada and Bermuda can find specific information on traveling to the U.S.

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 https://travel.state.gov/content/visas/en.html.
