Visitor Visa Sponsorship

[rghv28]

Hi,

My father-in-law and his sister(my mother in law is expired) are planning for visitor visa.

Have few questions regarding the sponsorship of the trip.

My father in law has bank account and other financial documents on his name and can self sponsor his trip.

His sister does not have anything on her name (like financial documents)

1. Can her son sponsor her trip? (If yes, what all the documents should we have to support their mother-son relationship)
2. Should I sponsor her trip?

My father in law and his sister will be attending the visa interview together.

Thanks in advance.

1. Yes.

You can show:
Your father-in-law's birth certificate to show who his wife is.
Birth certificates of your mother-in-law and her sister to show that they have common parents.

However, the above is really not required as anyone can sponsor anyone's visitor visa.

2.
Yes, if you want to.
