# COSCUP x UbuCon Asia 2026 — Invitation Letter Guide *(中文版本在下方 / Chinese version below)* --- ### TL;DR **Not visa-exempt and need a visa to enter Taiwan?** Request an invitation letter here: **🔗 https://forms.gle/woqnTfwBrpq1bbBAA** Then bring it to your **local Taiwan diplomatic office** to apply for a visa. The organizing team handles the letter — the visa application itself is between you and the consulate. > Your application will be reviewed by both the COSCUP and UbuCon Asia (UCA) teams, who jointly hold the right to approve or decline each request. Please make sure all information is accurate and clearly demonstrates your intent to participate in the event. **We strongly encourage you to apply early**, as processing takes time and visa appointments may have their own lead times. --- ## What Is an Invitation Letter? COSCUP x UbuCon Asia 2026 provides official invitation letters to support international visitors who need documentation for their visa application. The letter confirms your participation in the conference and may be submitted to a Taiwan diplomatic office as part of your visa application package. Each application is jointly reviewed by the **COSCUP** and **UbuCon Asia (UCA)** organizing teams. Both teams reserve the right to approve or decline any invitation letter request based on the information provided. Their decision is final. > **The invitation letter does not guarantee visa approval.** All visa decisions rest entirely with the relevant consulate or embassy of Taiwan (Republic of China). **Important:** The organizing team's role is limited to issuing the invitation letter. We are not able to advise on, assist with, or intervene in any part of the visa application process. You are responsible for contacting the appropriate Taiwan diplomatic office in your country and following their specific requirements. --- ## Step 1 — Check If You Are Visa-Exempt Visitors from eligible countries may enter Taiwan without a visa. **If you hold a passport from one of the 66 visa-exempt countries listed below, you do not need to apply for a visa or request an invitation letter.** *(List effective as of March 1, 2026)* 🇦🇱 Albania · 🇦🇩 Andorra · 🇦🇺 Australia · 🇦🇹 Austria · 🇧🇪 Belgium · 🇧🇿 Belize · 🇧🇬 Bulgaria · 🇨🇦 Canada · 🇨🇱 Chile · 🇭🇷 Croatia · 🇨🇾 Cyprus · 🇨🇿 Czech Republic · 🇩🇰 Denmark · 🇩🇴 Dominican Republic · 🇪🇪 Estonia · 🇸🇿 Eswatini · 🇫🇮 Finland · 🇫🇷 France · 🇩🇪 Germany · 🇬🇷 Greece · 🇬🇹 Guatemala · 🇻🇦 Holy See (Vatican) · 🇭🇳 Honduras · 🇭🇺 Hungary · 🇮🇸 Iceland · 🇮🇪 Ireland · 🇮🇱 Israel · 🇮🇹 Italy · 🇯🇵 Japan · 🇽🇰 Kosovo · 🇰🇷 South Korea · 🇱🇻 Latvia · 🇱🇮 Liechtenstein · 🇱🇹 Lithuania · 🇱🇺 Luxembourg · 🇲🇾 Malaysia · 🇲🇭 Marshall Islands · 🇲🇹 Malta · 🇲🇨 Monaco · 🇳🇷 Nauru · 🇳🇱 Netherlands · 🇳🇿 New Zealand · 🇲🇰 North Macedonia · 🇳🇮 Nicaragua · 🇳🇴 Norway · 🇵🇼 Palau · 🇵🇾 Paraguay · 🇵🇱 Poland · 🇵🇹 Portugal · 🇷🇴 Romania · 🇸🇲 San Marino · 🇸🇬 Singapore · 🇸🇰 Slovakia · 🇸🇮 Slovenia · 🇪🇸 Spain · 🇸🇪 Sweden · 🇨🇭 Switzerland · 🇰🇳 Saint Kitts and Nevis · 🇱🇨 Saint Lucia · 🇻🇨 Saint Vincent and the Grenadines · 🇹🇻 Tuvalu · 🇬🇧 United Kingdom · 🇺🇸 United States **Reference:** [外籍人士來臺免簽證適用國家名單 (Bureau of Consular Affairs)](https://www.roc-taiwan.org/cayyz/post/11744.html) Not sure if your country qualifies?

We are not able to assist with the visa application process itself, communicate with diplomatic offices on your behalf, or advise on visa requirements specific to your country. 4. **Eligible purpose:** Invitation letters are issued for visa application purposes only.

Decisions are made solely by the relevant consular authority. --- ## Note Regarding Certain Travel Documents Due to existing administrative and diplomatic constraints, **COSCUP x UbuCon Asia 2026 is currently unable to issue invitation letters for holders of People's Republic of China (PRC) passports.** We recognize that this limitation may be disappointing, and we sincerely regret any inconvenience this may cause. If you hold a PRC passport but have another valid residence visa or travel document, you may be able to find relevant entry information through the following resource: **🔗 https://coa.immigration.gov.tw/coa-frontend/overseas-foreign-china** We encourage affected individuals to explore alternative options or consult with the relevant consular offices directly. --- ## About COSCUP x UbuCon Asia 2026 COSCUP (Conference for Open Source Coders, Users, and Promoters) is one of the largest open source conferences in Asia, hosted annually in Taipei, Taiwan.
