I am going to start the visitor visa application process for my in-laws in India. My father-in-law has been to the UK once in 2014. My mother-in-law has been to the UK twice - once in 2014 and second time in 2015. They were both issued a visitor visa in 2017 on which they never travelled.
All of these times, my father-in-law's financial circumstances were different. He was employed full time so he was able to show stable income meeting his monthly expenses. This time though, he is going to be retiring next month without any pension from the employer. He does receive a tiny amount of pension (INR 2600 per month) from the provident fund. This has started very recently.
He has LIC policies that would mature in about a year's time. At the time of his retirement, he will receive his provident fund and gratuity which are very good sums of money.
I am going to be sponsoring their whole trip so they do not need to show any finances to support their trip. However, they will still need to provide evidence showing how they meet their ends. Are all the evidence I specified above enough in other's experience?
