I'm a retiree from United Nations after 20 years of service. During my service, I had visited UK many times officially with UN passport and privately with UK visa. I had a 5 years visa which expired in 2017. I have two daughters who are currently working in UK and both of them are EU citizens. My last visit to UK was in 2015.
Currently I settled in India and I would like to visit my daughters almost every year for few days. As I had a 5 years visa before, am I eligible to get a 10 year visa?
