It's never late.. I am 32 with a one year old kid and applying for my second masters degree. It is very common in countries like USA and UK to have some experience and then study further. So don't even think like that.

Hey Suma, Thanks for connecting! There is no age limit for doing a PhD, though, you need to have a research project/paper and something related published as well. International students are eligible for PhD funding through Research Council studentships, a generous form of financial support from an organisation called UK Research and Innovation. These scholarships provide PhD students with a monthly stipend for living costs, as well as a tuition fee waiver at the domestic rate. Hope this helps!
