I have a single visit Schengen-Visa Visa in Cultural category for Hungary. I am flying from Delhi to Budapest and my duration of stay is 10 days.
My question is, what if I want to go to the UK from Budapest directly by train via stations to stations. Can I travel by train from Schengen area to England in mythe given time in which I have in my Visa.? I have mya valid UK Visa in my Passport.
