Visitor Visa Question

Hi,

My mother recently visited UK and stayed here for about 5 months and we are planning to apply visitor visa again targeting travel after 4 months. I understand the visa/entry might be denied considering the reason around 'frequent visit may make UK as their main home'. However, the 2nd visit is mainly to support medical condition of my 2 year old child so just wanted to check if there is any chance of getting visa around the same and if not is there any other visa category that we can apply to bring my mother. Thank you!

How long did she state in her last application that she would be visiting the UK for? Did she state she was staying for 5 months?

She cannot be spending more time in the UK in a 12 month period than she does in her home country. That would be attempting to reside in the uk under the gyuse of being a visitor.

She also cannot come to the UK to be a carer for your child. That is considered working and not permitted on a visitor visa.

How long is she planning to stay if she gets another visitor visa? If she is refused entry to the UK, future visitor visa will become increasingly difficult.

There is no other visa that she likely qualifies for.
