I have refused your application for a visit visa because I am not satisfied that you meet the requirements of paragraph(s) 4.2 of Appendix V: Immigration Rules for Visitors because:
You have stated that you intend to visit the UK for tourism for 17 days. I understand that you have previously been refused three visas for the UK on 20/08/2014, 25/09/201 and 12/11/2015, and while each application is assessed on its individual merits, it is worth referring to your previous applications whilst considering your current application. I have considered your application with all the documents which you have submitted in its entirety and on a balance of probabilities I am not satisfied that you have demonstrated that you have met the requirements of Appendix V of the Immigration Rules.
You state in your visa application that you are retired and you have provided a pension letter. I am not satisfied that this documents, in isolation, adequately demonstrates your pension as you claim.
You state that your daughter will sponsor your trip to the UK. Whilst you have set out a bank document with funds for your sponsor I note that you have not demonstrated their personal and financial circumstances to substantiate the origin of their funds.
In light of all of the above I am not satisfied as to your intentions in wishing to travel to the UK now. I am not satisfied that you genuinely intend a short visit only to the UK and that you will leave the UK at the end of the visit. Furthermore, I am not satisfied that you will be able to maintain and accommodate yourself adequately in the UK or meet the costs of your return or onward journey from the UK. Additionally, I am not satisfied that your sponsor can and will provide you with support for the intended duration of your stay. Appendix V4.2(a)(c)(e) and V4.3(c).
