Heard a little better, BNO passports are just like the jade buildings in the air, look good, but in reality can not touch, since ancient times, the UK seems to have a rather strong resistance to immigrants, it is willing to welcome tourists from all over the world, but not willing to welcome “want to become British” tourists.
