Applying for a Visa

To prepare for your trip to the 2022 AACC Annual Scientific Meeting & Clinical Lab Expo in Chicago, we encourage you to find out as early as possible if you need a Visa.

Residents of certain countries may travel to the U.S. without a Visa under the Visa Waiver Program. If you do need a Visa, however, you should apply for one at least 5 months before the date of your intended travel.

Visit AACC’s International Travelers’ Assistance page for resources and quick tips on how to apply for a Visa, as well as information about the U.S. Customs entry process.

As part of your Visa application, you will also need a letter of invitation from AACC. Request a letter of invitation today.

The AACC Annual Scientific Meeting participates in the U.S. Department of Commerce’s Trade Event Partnership Program, which connects international customers and buyers with U.S.-based suppliers.
