You must prove that:
you have a frequent and ongoing need to come to the UK
the reason why you need to come to the UK is unlikely to change while your visitor visa is valid
you plan to leave the UK at the end of each visit
You may be given a visa for a shorter period than requested if you don’t do this. You won’t get a refund of the application fee if you get a shorter visa or your application is refused.
Your visa may be cancelled and you may get a long-term ban on visiting if your travel history shows you’re repeatedly living in the UK for extended periods.
