Family visitor visa for a student

[Alex3977]

Hello,
I, my wife and my son are British citizens.

I want to invite my niece to visit us on a family visitor visa. My 20-year-old niece is an Indian citizen and currently on a student visa (2nd year on) in Georgia. She has a temporary residence permit until 2030 to finish her studies there.

She wants to travel here from mid-July to mid-Sept only when her university is closed for summer vacation.

She will provide her university enrolment letter, temporary residence permit, study fees confirmation letter, and consent letter from her parents (my sister & brother-in-law).

Please advise which other documents from her side can make her application stronger.

Thanks!
