Questions regarding directorship, salary, dividend

[i_m_in]

I used to be on a Tier-1 work visa. I am the only director of my UK limited company and worked as an IT contractor through my limited company till when my visa was valid. The visa expired in early January. I did not extend my visa, and on the date of visa expiry, I left the UK and returned home for good. Am I legally allowed to continue being the director of my limited company after the expiry of my visa? Am I allowed to continue drawing salary and dividend after the expiry of my visa? There hasn't been any money incoming into the company since the time I left the UK, but there is money left in the company account, part of which I am thinking to pay myself in the form of salary and dividend IF doing so does not break any law. Ofcourse I will ask my accountant as well, but from previous experience he doesn't seem to have much experience of non-EU clients on UK visa, that's why I am taking the opportunity to ask on this forum as well.
Many thanks for your kind advice.
