I have refused your application for a visit visa because I am not satisfied that you meet the requirements of paragraph(s) 4.2 and 4.3 of Appendix V: Immigration Rules for Visitors because:
You have provided details of a sponsor and provided letter of invite, however, in order to be able to make a decision on whether or not to grant you entry clearance in this category I must take into account your stated personal circumstances in Russia, the reasons for your visit and your proposed travel arrangements.
You have declared that you are employed as a Teacher of Technologies at *****, earning £937 per month, you will travel to the UK for 14 days and you have £380. You have provided a bank statement which states you have RUB 90,800.00 (£1,189.79) within this account but I have been unable to establish the source that created this amount. In addition, from the information you have provided, I have been unable to confirm that you receive any form of proven monthly income from the salary you state being deposited into a bank account in your name and I am therefore not satisfied that you will have sufficient funds to provide for yourself for the whole duration of your visit.
You state that you will visit a family friend who resides in the UK and you have provided a letter of sponsorship and passport, however, from the information provided, I have been unable to establish their current financial circumstances and that they are able to provide you with all maintenance and care and have adequate accommodation to provide for you for the whole duration of your stay.
From the information provided, I have not been able to confirm your receipt of a regular proven income, nor of how you are supported on a daily basis or of any family members currently in Russia. As such I am not satisfied that you have provided an accurate portrayal of your current personal circumstances.
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 are genuinely seeking entry for a purpose that is permitted by the visitor routes, not satisfied that you will leave the UK at the end of the visit and 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. Your application is refused under Appendix V4.2 (a) (c) and (e) of the Immigration Rules.
Furthermore, I am not satisfied that it has been demonstrated that you have a genuine professional or personal relationship with your sponsor, and that they can and will provide support to you for the intended duration of your stay in the UK. Your application is also refused under Appendix V4.3 (a) and (c) of the Immigration Rules.
