What are two requirements to apply for permanent residency or citizenship in the UK?

To become a permanent resident or citizen in the UK, demonstrating integration into British society is key. This goes beyond simply living in the country; it involves showing you can participate fully. That's why proving your English language skills – both speaking and reading – is essential. It ensures you can communicate effectively in everyday life, access services, and contribute to the community. Similarly, having a "good understanding of life in the UK" is crucial. This means knowing about British history, culture, laws, and values. It demonstrates that you've made an effort to learn about and integrate into the society you wish to join permanently. The Life in the UK test itself is designed to assess this understanding. While renewing your passport or getting a driving license are important for practical reasons, they don't demonstrate integration. And while the Home Office is involved in the application process, simply going there doesn't fulfill any requirements in itself.
Think of it as needing to understand the language and the culture to become a citizen.
