I met my ****Romanian**** friend through a friend here in the Philippines during his vacations together with his friend for two weeks. He is a Romanian living and working in London for 5 years already.
In just a short period of time, I and he including his two other friends(Romanian and Filipino living in New York, USA) became very close and really enjoyed each other's company.
So when they left he( Romanian friend living in the UK) mentioned that if I wanted to visit London in the future for a short vacation trip he said that he can sponsor me by giving me accommodation, providing my day to day expenses, like leisure and etc.
My question is, is he allowed to be my sponsor? I'm planning to visit London for a week trip in August or September 2019.
