We had applied for my father in law's visitor visa in 2020.We got a reply in Feb 2023 saying that it has been rejected and the reason being that he has no strong ties which is weird as his wife and his elder son live in India and he has no intention of settling here.He just wants to visit us and go back.He has no property in his name.We are not showing any funds in his name as he is retired and it is completely sponsored by my husband and we are showing 25000$ in my husband's account.My mother in law already has a visitor visa and she wishes to travel with my father in law.Please suggest what else needs to be done to increase his chances of getting accepted 2nd time.Thank you
