Visa Information for International Travelers
The U.S. State Department Web Site, travel.state.gov, has information about obtaining a visa for those traveling to the United States. This site has links to Web sites for U.S. embassies and consulates worldwide. The embassy and consulate Web sites have very helpful information about procedures, timelines, communities served, required documentation, and fees.
If you are traveling to the United States for tourism or business for 90 days or less, you may be eligible to visit the US without a visa. For complete and updated information on requirements for this program, please see the US State Department's page on the Visa Waiver Program.
Also be aware that the U.S. Department of Homeland Security has recently enhanced its security requirements for international travelers who are citizens of countries covered by the Visa Waiver Program. Information about these requirements is available from the Electronic System for Travel Authorization web site. In particular, travelers are expected to apply at least 48 hours prior to departure. We also understand that you should have your hotel's street address handy when you go through U.S. Customs. You can find the address of the conference hotel on our accommodations web page.
The Association for Computing Machinery (ACM, SIGCSE's umbrella organization) does not issue formal invitation letters for visas. However, they can issue a visa support letter. For a visa support letter, please send a request to email@example.com with the following information:
- Name and mailing address as it appears on your passport
- The name of the conference you wish to attend (SIGCSE 2013)
- Registration confirmation number
- If you are the author of any papers accepted for the conference, please provide the title
- Fax number (visa support letters are not issued via email)
