i had my gf over a few times. The main thing is to prove funds, at least £150 for everyday that she is there and an itiniery. Showing places you two will visit price of hotel, food roughly we just put 50 per day for food hotel price per night and entrance fees for places, she needs letter from her manager at work to show she is going to return home payslips for last 6 months if i remember correctly proof she has her own property contract for rental or book for home dont over think just coach her on what they may ask her why does she want to visit? She is going to visit her boyfriend, she will stay with you and that she has an interest in the history of england, wants to experience a different culture and that she will be visiting places with you. M me i can give you an itiniery to show you your side but the main thing is the bank statements, proof of home and enough money to cover her trip, letter from her manager just saying she has leave to go to uk between x and y dates
