Conference Registration

Coming soon

Visa support

Visa support letters can be issued to attendees as well as authors with accepted papers, posters, or members of the conference committee. Those requesting a letter should allow up to one week to receive it, as requests are handled in the order they are received. The deadline for receiving requests for support letters is the same deadline for early registration.

Please send all visa letter requests with the following information to supportletters@acm.org:

– Name (as appears on attendee's passport) and mailing address
– The full name of the MobiSys conference: The 15th International Conference on Mobile Systems, Applications and Services (MobiSys 2017)
– Conference registration confirmation number
– If you are the author of any papers accepted for the conference, please provide the title. If you are a speaker, please provide the title/topic of your speech.
– Include a fax number or email address of where letter can be sent


ACM does not provide letters for transport of vendor or presenter equipment.
