This Refund & Payment Policy applies to all SIP2026 registrations, services, and related payments. By completing registration or payment, participants agree to the terms outlined below.

Refund eligibility depends on the timing of the written cancellation request received by the Organizer:

• - Before 120 days prior to the conference: 70% refund (30% administrative & processing fee).
• - Between 90 and 60 days prior to the conference: 40% refund.
• - Less than 60 days prior to the conference: No refund.

All refund requests must be submitted in writing to join@sip2026.org.

The following fees are non-refundable once paid:

• - Invoice request fee (USD 20)
• - Invitation letter or visa support processing fees
• - Abstract/paper withdrawal processing fees

Visa delays, refusals, travel restrictions, personal emergencies, or employer decisions do not override the refund timeline. Refunds, where applicable, are processed strictly according to the dates defined in Section 2.

Participant substitution from the same organization or institution may be permitted prior to the conference, subject to organizer approval and administrative conditions. Substitution does not guarantee refund eligibility.

SIP2026 reserves the right to adjust the event format (onsite, hybrid, or online) due to safety, regulatory, or operational needs. Such changes do not constitute cancellation and do not qualify for refunds beyond the defined refund timeline.

Refunds must be requested directly from SIP2026. Initiating chargebacks or disputes outside this Policy may result in cancellation of participation, withdrawal of services, and publication ineligibility.

This Policy is governed by the laws of the State of California, USA. SIP2026 may update this Policy as needed; the most recent published version shall apply.
