The state language. The founding documents are filed in Uzbek — how the company then operates is separate.
The regulation attaches the founding documents to the request in the state language, and repeats the requirement for the documents filed on a capital increase or a share transfer. That is a rule about the filed instrument, not about the company’s working life: nothing in the registration act tells a company which language to hold meetings, keep books or write contracts in.

The register itself accommodates more than one language. Its content list records the full and short company name in the state language and, where the founding documents give a name in a foreign language, that name as well. A bilingual charter is therefore a drafting choice rather than something the procedure forbids — what the registrar receives has to be in Uzbek. (State Register Regulation, Para. 5 — lex.uz ↗)
