As of now (Jan 2018) Tier 1 Exceptional Talent Visa fee is 585 GBP (£ 292 on the Endorsement Stage and £293 on the Visa Stage). The applicant must pay them to process the visa application further. However, shall the applicant pay these sums by himself? Are visa fees not paid by an applicant real?
My potential employers in the UK intend to pay for my Stage 2 visa fee and they have requested that I provide them with the available options for payment. Do you have any idea of how a potential employer can pay for an applicant visa fee on the Visa4UK website?
At the same time, I suggest that there is an exceptional case. If your employer is a flexible and fast-working person and you trust them so much, you can share your login details with him. He can try to pay visa fees for your talent visa application, being logged as you. However, mind the obvious risks! Honestly, I recommend this way only if you cannot use any other option.
