If you are a dependant partner, spouse or child of a person with work visa in the UK, you can apply for dependant visa to join or stay with the work visa holder in the UK. The dependants of work visa holders are normally granted permission to stay in the UK until the expiry of the leave granted to the work visa holder who is sponsoring their stay in the UK. In most categories of work visas, the dependants of work visa holders can apply for ILR in the UK upon completion of 5 years in the UK on dependant visa. In some cases, the dependants can apply for ILR at same time when the main applicant is applying for ILR regardless of the length of their residence in the UK.
