I have used all the information provided by you to determine if the requirements of the Immigration Act have been met. In reaching my decision, which has been made on the balance of probabilities, I note the following points:
You have applied for entry clearance to the UK to study the English language for 5 months and 14 days. You have stated that you are employed as a photo editor and earn £11,300 a month from this. As evidence of this you have submitted a letter. However, this does not state that you earn this income but rather 80,000 RUR a month. However, the bank letter and statement do not reflect your income or show where the funds come from and I am therefore not satisfied that you earn the income stated or that these funds are genuinely available to you for your proposed studies in the UK. You have also state that you have a secondary source of income but have provided no evidence of this.
It is not clear from the information you have provided why you want to study the English language now or whether you have sought to study it before in Russia. On your Visa Application Form you have stated that you applied for a visa for Germany in January 2018 to study German but that your application was refused. It is not clear why you only now want to study English rather than German. You are proposing to pay £7500 to study English in the UK. I do not find this to be credible given the information and documents you have submitted.
Taking all the evidence into consideration I am not satisfied that you are genuinely seeking entry as a short-term student (A57C (ix)) or that you intend to leave the UK at the end of the study or at the end of 6 months whichever is sooner (A57D (b)).
I have therefore refused your application because I am not satisfied, on the balance of probabilities, that you meet all of the requirements of the relevant paragraph of the United Kingdom Immigration Rules. In relation to this decision there is no right of appeal or right to administrative review.
