I am a Russian citizen who is invited to do a job interview at a company in London. The company will pay for my travels, accommodation, visa fees and have provided an invitation letter (which clearly also states that). For this, I need to get a visa for the UK.
Since I'm not yet employed, I can't provide a letter which states my regular income. However, it is the main requirement for the application process for a Standard Visitor Visa.
Instead, I could attach a letter showing the amount of money I have on my bank account. I read many times that it is often the reason for refusal that the source of income is not specified.
What would be the best option for me in this case? Will it be enough to show a copy of recent transactions, along with the invitation letter?
