To obtain a child visa for the UK, parents or legal guardians must submit the child's passport, a completed visa application form, a recent passport-sized photo, and proof of relationship. Additionally, financial documents demonstrating the ability to support the child during their stay, as well as a letter of consent from both parents, may be required. The child should also undergo a tuberculosis test if applicable. It is essential to check the latest requirements on the official UK government website or consult with a visa advisor for up-to-date information.
