The American Consulate General in Thessaloniki does not issue visas. The Consulate can provide general information and informative handouts to visitors via telephone and at the Consulate lobby.
Below we provide information reproduced fom the U.S Embassy Athens website Visa information pages.
The Athens Consular Section provides visa services to Greek and third-country nationals, including nonimmigrant and immigrant visas.
On occasion, some travelers may experience delays at the port of entry due to the result of extended computer checks and/or secondary inspection by the Department of Homeland Security. The US State Department does not have the authority to intervene with DHS on the behalf of individual travelers. However, if you feel you have been subject, in error, to a delay at the port of entry, you may request an audit of your case by visiting the DHS redress website.
