UK visa sponsor

Question

I'm applying for a UK visa to sit for plab exam, and I am thinking about making my dad a sponsor. I have two questions:

My father runs a private clinic, so providing an evidence of the average income will be hard. Will that affect the decision, and if yes how can I provide acceptable evidence of his income since he receives money in cash?

His bank account contains enough money but with too few transactions, as the money is derived from saving certificates interest. Will that bank statement be accepted?

Answer 1

I think you could include the savings account statements along with your main statements. This will help show where your money came from.

Does he keep company accounts? Tax records? Even a cash business should do this.
