Fee quote needed - a quick advisory for Tier 4 student visa

Hello, I need a fee quote from a UK immigration advisor who is familiar with Tier 4 Student visa please.

Background:
1: My Japanese HNW individual client, her son (will be 18 yrs old next month) has been studying in the UK for approx 8 years and he is currently under Tier 4 student visa.

2: His parents are based in Japan, and running several businesses in Japan. For the Japanese tax purposes, the son has been appointed as a "part-time director" for his parents' company since January 2026 and he started to receive the director remuneration (just 400 to 500 GBP per month) since then.

3: The mother is now concerned that receiving director remuneration could be a breach of Tier 4 student visa.

4: As the son is studying in the UK, although he was registered as a part-time director in Japan, he is literally doing nothing as a director (i.e. not active). It's just for tax planning purposes for his parent's company in Japan.

5: The mother confirmed that she can retrospectively change the son's director remuneration to "dividend" if necessary.

I need an immigration advisor who can advice on the above, i.e. 1) is it ok for the son to receive director remuneration if he is "not active"? 2) Is it advisable to switch to "dividend"? 3) Is it advisable that the son returns all the remuneration to the company and will not receive any director related remuneration?

Just an email advisory should be sufficient but please provide the relevant Home Office link etc as supporting documents. The client may ask some follow up questions so please take it into account when you prepare your fee quote.

The work is not yet won. The client would like to see your fee quote and then decide.

Many thanks.
