I wish to know if anyone has an experience dealing with the following: Husband and wife travelling together to the UK on a visitor visa for 1 month leaving their 7 and 12 year old children with their grandparents. Do I need to provide any documents relating to this situation with regards to our children?
You will be asked on the application form if there are dependents you’re temporarily leaving behind.
That section is exactly for the situation you describe.
Here is a screenshot of that section. You can add as many dependents as there are, and you will have to answer the following for each one of them.
