No visa or residence permit requires a language test — Indonesian only becomes a legal requirement at naturalisation, and the official instrument to evidence it is the UKBI.
Overview
Indonesia imposes no language requirement at any visa or residence-permit stage: work (E23), investor (E28A), golden visa, second home, retirement and remote-worker indices, ITAS extensions and even the permanent ITAP are all granted without any test of Indonesian. The legal language requirement appears only at naturalisation: Law No. 12 of 2006 on Citizenship requires applicants to be able to speak Indonesian (alongside acknowledging Pancasila and the 1945 Constitution). The state's official proficiency instrument is the UKBI (Uji Kemahiran Berbahasa Indonesia), developed by the Language Development and Fostering Agency (Badan Pengembangan dan Pembinaan Bahasa) and delivered since 2021 as the online adaptive 'UKBI Adaptif Merdeka' via ukbi.kemdikbud.go.id. The published tariff for foreign nationals is IDR 1,000,000 per sitting (Indonesian general public IDR 300,000; students less), certificates are valid for two years, and retakes are allowed after 15 days. For learners, the government supports BIPA (Bahasa Indonesia bagi Penutur Asing) programs at universities and language centres in Indonesia and abroad. Verified against ukbi.kemdikbud.go.id and Badan Bahasa regional offices as of June 2026.
Where Language Does — and Does Not — Apply
| Milestone | Language requirement | Evidence |
|---|---|---|
| Visit visas (C/D indices) | None | — |
| Limited stay permits (all E indices, incl. work E23) | None | — |
| Permanent stay permit (ITAP/KITAP) | None | — |
| Naturalisation (Law 12/2006, Art. 9) | Able to speak Indonesian; acknowledge Pancasila and the 1945 Constitution | Assessed in the naturalisation process; a UKBI certificate is the standard objective evidence |
| Professional contexts (e.g., foreign health workers) | Sector rules may require Indonesian competence for practice/adaptation | Set by the sector regulator, not immigration |

Do I need any language test for an Indonesian visa or KITAS?
No. No visa index — work (E23), investor (E28A), golden visa, second home (E33), retirement (E33E/F) or remote worker (E33G) — and no ITAS extension or ITAP application requires evidence of Indonesian. The official requirement lists on imigrasi.go.id contain financial, sponsorship and documentary items only. The first time the law asks about language is naturalisation under Law 12/2006, which requires the ability to speak Indonesian. Sector regulators can separately require language competence for licensed professions, notably foreign health workers in their evaluation and adaptation process.
What is the UKBI and who administers it?
The Uji Kemahiran Berbahasa Indonesia is the state's standardised Indonesian proficiency test, developed and administered by the Language Development and Fostering Agency (Badan Pengembangan dan Pembinaan Bahasa) under the education ministry, with delivery through provincial language offices. Since 2021 it runs as UKBI Adaptif Merdeka, an online computer-adaptive format whose item difficulty adjusts to the test-taker. Results are expressed in seven ranks from Terbatas to Istimewa. Register and sit it via ukbi.kemdikbud.go.id; certificates are issued electronically and are valid for two years.
How much does the UKBI cost for a foreigner?
The published tariff for foreign nationals (WNA) is IDR 1,000,000 per sitting — distinctly higher than the IDR 300,000 general-public rate for Indonesian citizens and the reduced student rates. Payment is by billing code generated at registration on ukbi.kemdikbud.go.id. If your result disappoints, you can retake the test 15 days after the previous sitting, as many times as you wish, paying each time. For most foreigners the spend is occasional — typically once when solid evidence of proficiency is needed for a naturalisation file, study or employment.
What exactly is the language requirement for Indonesian citizenship?
Article 9 of Law No. 12 of 2006 requires a naturalisation applicant to be able to speak Indonesian and to acknowledge Pancasila and the 1945 Constitution — alongside the residence (five consecutive or ten non-consecutive years), age, income, health and criminal-record requirements, and renunciation of existing citizenship. The statute sets no specific test score or named certificate, so assessment occurs within the naturalisation process administered by the law ministry; in practice a UKBI certificate is the standard objective evidence applicants attach. Treat conversational competence as the realistic bar, not perfection.
Where can I actually learn Indonesian properly?
Through BIPA (Bahasa Indonesia bagi Penutur Asing) — the government framework for teaching Indonesian to foreign speakers, offered by university language institutes (in Jakarta, Yogyakarta, Bandung, Denpasar and elsewhere), Badan Bahasa partner centres, and Indonesian embassies abroad. Course levels align with proficiency frameworks and feed naturally into UKBI preparation. Indonesian is comparatively learner-friendly — Latin alphabet, no tones, regular grammar — and daily exposure is immediate outside expat bubbles, so most committed learners reach functional competence well within the five-year naturalisation residence period.
Is English enough to live in Indonesia?
In Bali's expat corridors, tourist zones and multinational Jakarta offices, largely yes. In the systems this guide covers — police stations issuing the STM, Dukcapil counters, immigration offices outside the big hubs, banks in secondary cities, tax paperwork — Indonesian dominates, and forms are in Indonesian. Many eVisa and ministry portals offer English versions, and immigration accepts some civil documents in English without translation, but the day-to-day administrative reality rewards even basic Indonesian quickly. If you intend permanence (ITAP, citizenship), start early: the citizenship statute makes speaking Indonesian a legal requirement.
