Ownership and directorship are not immigration status
Company law treats being a shareholder or director as separate from employment or the right to work. A non-resident can hold every share, sit as the sole director, sign contracts and take dividends without ever needing UK immigration permission, provided they do not physically work in the UK.
Problems arise if a non-resident director starts actually performing substantive UK-based work, such as regularly attending an office or managing UK staff on the ground, since that can shift into needing a work visa regardless of their shareholding.
