## Why this rule exists

US reviewers assess against US requirements in English, and a sample they cannot read cannot be checked for the disclosures and content rules everything else depends on. Sending in other languages is fine — the registration artifact needs to be readable.

## How to fix it

Supply the samples in English. Where the programme genuinely sends in another language, include both the original and an English translation in the sample.
