Important information:

• At least one author of each accepted paper must register and pay full registration fee ($550) by 5 October 2026.
• All registrations associated with accepted papers should be made before 5 October 2026
• If you have more than one accepted paper, you have to register for each one individually.
• The registration fee includes admission to all conference sessions, conference proceedings, coffee break refreshments, lunches and gala diner.
• For other registration (non-authors, co-authors, or full time students but not to register the paper), a 100 USD handling fee will be applied if the cancelation is before 15 October 2026. Fees cannot be refunded for registrations canceled after 15 October 2026.

Additional information:

1. One registration per email address. Because each accepted paper needs its own registration, use a different email address for each additional paper. If you start again with the same email address before paying, your unfinished registration is replaced.
2. Optional extras must be selected on the registration form (they cannot be added to an existing registration online): extra gala dinner ticket, 100 USD each (up to 10 per registration); extra camera-ready page, 50 USD each (up to 3 per registration; enter the ID of the paper it is for).

Financial support:

• Authors with papers conducted in Vietnamese universities can apply for financial support by sending an email to csonetorg@gmail.com from the email used in paper submission. The email must include paper ID, paper title, and affiliation of all authors.
• We also have some limited support for non-authors from Vietnamese universities (especially students). Email to csonetorg@gmail.com for more details.
