Parent of the Child student Visa:
If your child has a child student Visa or studying in the UK on a Tier 4 child Visa, you can get the parent of the child student Visa. Your child must be enrolled in an independent school in the UK and age must range from 4 to 11. You are the only parent attending your child in the UK, proof of sufficient money to support yourself and your child in the UK and have no plan to stay in the UK after the visa expires.
As a parent, you can be able to bring your other children with you, but all your children must apply for a Child visa for the UK. You can stay in the UK until your child turns 12 or your visa gets expired. The facility to extend the visa is available after meeting the eligibility criteria. You do not do study, work on payment, and business on the parent of the child student visa.
