Hello Vivianmanila, a warm welcome aboard Filipino UK

Good luck with your visit visa application.

Were you able to counter previous visa refusal reasons by submitting clear supporting documents showing strong social, economic and family ties in Philippines?

Who will shoulder the finances for the visit?
If it's your BF did you submit evidence of his financial capability to support you for the duration ofthe visit? Including all bank statements.

It's quite a significant requesting a 6 month stay.....But all best of luck anyway.
