Women in SIGMM - Lunch invitation

Visa Information

The travel.state.gov site has information about obtaining a visa for those traveling to the United States. The site also has links to websites for U.S. embassies and consulates worldwide. The embassy and consulate websites have very helpful information about procedures, timelines, communities served, required documentation, and fees.

International registrants should be particularly aware and careful about visa requirements and should plan travel well in advance.

The Association for Computing Machinery does not issue formal invitation letters for visas. We can however issue a visa support letter (note that it can take up to 7 business days to receive the support letter from ACM). All visa inquiries must be handled by ACM HQ. Please send your request for a letter in support of a visa application to supportletters@acm.org and include the following information:

  • Name and mailing address as it appears on your passport
  • The name of the conference you wish to attend
  • 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)
