ACM FAccT 2025 Visa Information

If you need a visa, please check with the Greek embassy or consulate closest to you for the proper visa process you must follow. Below we cover two of the most common processes: that which applies to citizens from visa-exempt countries, and that for nationalities that need a Schengen Visa.

Visa exempt countries

There are some visa-exempt countries for Greece, including but not limited to the US, UK, Australia, UAE, Brazil, EU nations, and many others. You can check this government visa page to see whether citizens from your country are exempt from needing a visa to enter Greece..

Schengen Visa

Nationals from countries that are not visa-free should apply for a Schengen Visa, according to the procedures of the corresponding Greek embassy or consulate. If you already have a Schengen Visa, you will just need to ensure it is valid for the conference dates.

Neither ACM nor FAccT has any control over the visa application process, so we recommend submitting the application as soon as one can, if possible, without waiting to receive a visa support letter (see more info below).

Please note you will need a Schengen Visa (Type C) for a short-term stay: please see this link for the full set of documentation required to submit your visa application. You will be required to write a cover letter that contains a personal statement on the purpose of your visit.

Visa Support Letters

ACM is the professional organization with which FAccT is affiliated. ACM is able to provide visa support letters to attendees as well as authors with accepted papers, posters, or members of the conference committee. ACM does not provide formal invitation letters. For ACM-supplied visa support letters, refer all requests to supportletters@acm.org and allow up to 10 business days to receive a letter from ACM. The information below should be included with the request: Your name as it appears on your passport, Your current postal mailing address, The name of the conference you are registering for, and your registration confirmation number (not necessary for an accepted author). If you have any papers accepted for the conference, please provide the title and indicate whether you are the “sole author” or a “co-author.” Authors may indicate their paper title. If no paper, speakers can provide the title of their presentation.

Request a visa support letter from the ACM

An alternate method of receiving a visa-support letter for FAccT 2025 is available as needed. We are also partnering with Archimedes Research, our local partner, to produce invitation letters from a Greek entity. If your process requires or would benefit from a visa support letter from a Greek organisation, Archimedes Research can provide you with one. Please use the form below to request a visa support letter, and allow up to 10 business days to receive a letter, beginning April 11. All requests are handled in the order they are received.

Things to Note

• We recommend that you submit your visa application as soon as possible. The processing time for a Schengen visa typically takes up to 15 calendar days from the date of your application. However, the exact time may vary depending on factors such as the embassy or consulate you apply through, the time of year (peak travel seasons may cause delays), and whether additional documents or interviews are required. In some cases, the processing time can be extended to 30 days or, in rare instances, up to 60 days if more documentation is needed.
• Authors of accepted papers only: you may request a visa support letter prior to registering for the conference. All others may only request a letter after registering.
• Make sure you complete all parts of your visa application. Submitting an incomplete application has been a common problem resulting in visa application rejection in prior years.
• Carefully read all instructions for the required forms and adhere to them strictly. Errors in your application may require you to reschedule your appointment.
• Note that Greek embassies do not reimburse Visa fees if the application is denied. We will, however, reimburse your registration fees if your visa is denied.
