Visa to UK

I didn't want to read this and run, but hopefully someone will be along to provide better advice than what little I know! Does your family have anything that shows they have a house, either owned or rented? I presume that your mother is retired, so proof of work would not be an option?

Good grief, ignore me! Perhaps showing something that says she is working and has a job that expects her presence?

Good luck, M2R2. If they applied that logic to everybody, nobody would be let in as anybody could decide to stay, connections to their home country or not! I would just focus on getting as much proof as possible that your mum has responsibilities back home and therefore isn't an 'overstay' risk. Hope she gets her visa.
