If it was your first attempt...you must prove a connection....pictures together.....send her money....prove of correspondence....most of all....tell the truth....you would be supporting her and show them the funds in your stash ....but since it's the forth attempt, am guessing you have been economic with the truth ...only course now is a agent and am thinking that would be a complete waste of money....as far as the British embassy is concerned now, You've had your go and your blacklisted for 5 years....in my humble opinion 😕
