Dependants normally include your spouse or partner and children. If your dependants or any other family members would like to come with you, they can apply for a Standard Visitor (tourist) visa. Children of visitors cannot attend state schools.
The conditions and restrictions for your family will be the same as you if you are coming in as a Standard Visitor (Business Visitor).
Family members will also not be entitled to free healthcare under the UK National Health Service (NHS) and must get private health insurance before travelling to the UK.
