IETF | Visas and Letters of Invitation

The IETF works on a broad range of networking technologies that provide the foundation for the Internet's growth and evolution.
While most IETF work takes place online, meetings and other events such as Hackathons provide in-person opportunities to advance work within the IETF.
The IETF is the premier Internet standards organization. It follows open and well-documented processes for setting these standards. Once published, those standards are made freely available.
The global IETF community works together in many different ways to produce high quality, relevant technical documents that influence the way people design, use, and manage the Internet.
By supporting the IETF today, you are ensuring a free and open Internet exists tomorrow.
This webpage provides information for various options to obtain authorization to travel to IETF Meetings. It is updated as registration for future IETF meetings open.
Unfortunately, fraudulent registrations are sometimes used to obtain IETF letters of invitation for the purposes of visa fraud and so we actively work to detect and prevent this. If we determine that a meeting registration is fraudulent, we cancel the registration and report the fraudulent registrant to the visa authorities in the country in which we expect that visa application to be made. In addition, if we determine that a stolen credit card was used as part of this fraud then we refund the card.
To determine if you require a visa please visit the US Visas page via the U.S. Department of State, Bureau of Consular Affairs website.
If you require a visa, a letter of invitation will be available during registration or at a later date from your participant dashboard.
Visa requirements for entry into Malaysia vary depending on nationality. Participants should check the official Immigration Department of Malaysia website to determine whether they require a visa and what requirements apply:
Malaysia visa requirements by country
Participants who require a visa may be eligible to apply through Malaysia's official eVISA system:
Malaysia eVISA portal
We strongly recommend checking your entry requirements and beginning the visa application process as early as possible. Visa requirements and processing times are determined by the Malaysian authorities and may change.
If you require a Letter of Invitation (LOI) to support your visa application, one will be available after you complete registration for IETF 128. You can access your LOI through your IETF participant dashboard.
An IETF LOI confirms your registration and the details of the meeting. It does not guarantee that a visa will be issued. Visa decisions are made solely by the relevant Malaysian authorities.
Foreign visitors may also be required to complete the Malaysia Digital Arrival Card (MDAC) before entering Malaysia. The MDAC can only be submitted within three days of arrival in Malaysia.
Participants should review the current requirements and, if applicable, submit the MDAC using the official Malaysian Immigration Department website:
Malaysia Digital Arrival Card
Participants are responsible for ensuring that they have the appropriate passport, visa, entry authorization and other documentation required to travel to Malaysia.
Please use official Malaysian government websites when applying for a visa or completing entry requirements. The Immigration Department of Malaysia advises that its official eVISA portal is the only official website for Malaysian eVISA applications.
