I got my UK citizenship as husband of HSMP (Doctor). Have been in UK since 1995. My father does not require care at present as he is in good state of health.
Can I apply for a long term visa instead that allows him to stay with me for a few years retaining Indian citizenship?
He is on a 6 month visa but if I recollect correctly 10 year visas were also available. Can I do it from the U.K?
