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.
I have noted your sponsor’s circumstances in the UK and his supporting documentation but the onus is on the applicant to demonstrate that they meet the requirements of the Immigration Rules.
You state it is your intention to travel to the UK for 4.5 months to stay with your partner and then travel with him to the USA for an unspecified duration before returning to Russia. You state you have been a receptionist for an affiliate of ***** since April 2017 and I note an employment letter has been provided. This letter, with a typo in the English translation, does not demonstrate that an extended leave of absence has been granted or indeed that they are aware of your intended leave of absence. The documentation does not establish your future travel plans. As such I am not satisfied that you will have an employment position to return to, or that you intend to depart the UK as stated by you.
I am not satisfied that you meet the requirements of 4.2(a) or (c) of Appendix V. Any future UK visa applications you make will be considered on their individual merits, however you are likely to be refused unless the circumstances of your application change.
