*Denotes non-CME Session/Event

Charlotte Douglas International Airport (CLT) is the main airport in Charlotte. CLT is located approximately 7.3 miles to the Charlotte Convention Center (501 S. College Street, Charlotte).

Taxis or rideshares (Uber, Lyft) are commonly used and available at the airport.

To enter the United States, international travelers are required to have a valid passport. A visa is required for the citizens of countries that do not have visa-exempt agreements with the U.S.

Please visit the U.S. government travel site to confirm if you would require a visa in entering the U.S.

Please contact your local United States Consulate to learn more about visa acquisition. Please note, SRS is unable to submit a visa application on the registrant’s behalf. The decision to grant visas is at the sole Discretion of the embassy/consulate. The meeting organizers cannot change the decision of the governmental agency should your application be denied.

Advance travel planning and early visa application are important. It is recommended that you apply early for your visa.

In September, the average high-temperature in Charlotte, NC is 82°F (28°C), and the average low-temperature is 62°F (17°C).

Charlotte will be in the Eastern Daylight Savings Time (EDT) during the Annual Meeting, which is three (3) hours ahead US Pacific Daylight Time (PDT) and four (4) hours behind Greenwich Mean Time, GMT-4.

Charlotte operates on a 110-120V (60 Hz) supply voltage. For the U.S. there are two associated plug types, types A and B.

Type A = Two flat parallel pins

Type B = Two flat parallel pins & a grounding pin
