Hello everyone! I've got few questions here, hope someone will be able to help

I am here in the UK with ILR and I'd like my mum to come over to visit me, preferably on Xmas

I've been reading https://www.gov.uk/standard-visitor-visa/overview and https://www.gov.uk/government/upload...2__-_CLEAN.pdf

Now the questions....

1. Does she need to provide proof of income? She rents one of our houses out and some small rooms at the back of our house where she lives but it's not a registered business. What can she provide instead?

2. Does she need to show that she has properties that she'll be going back to after she visited me? She has papers for the houses but used my dad's surname for years (which shows in papers) and their marriage is not registered so she won't be able to show she's married. Will this be a problem?

3. If I were to sponsor her, is it gonna be easier? What do I need to do and what papers do I need to provide?

I had tons of questions before signing on here and can't remember all of them now ... hope I'll be able to get help from you guys. Thanks in advance.
