The requirements for UK Dependant Visa holders change according to the main visa holder's visa classification but typically involve relationship validation (spouse, civil partner, child), financial dependency evidence (e.g., bank statements), and appropriate housing documentation. The age limit for dependent children is under 18 years unless they demonstrate financial dependency on the main visa holder. Dependent adults must show they have sufficient financial resources to support themselves. The visa subclass may require dependants to fulfill English language standards together with other particular criteria.
