usa – I’m a UK citizen/resident employed remotely by a US company. What’s the chances of getting an H1B visa?

I’m a UK citizen working in London. For three years, I have been a writer employed by a company based in the USA. It’s fair to say I’m indispensable but I do not have any formal writing qualifications.

I want to ask my employer about sponsoring a work visa for me so I can stay in America for a while. From what I understand, an H1B is the best option? But before I bother them, I’d like to know if I’m overlooking something and it’s a waste of time? Or is there a chance?

The biggest issue is that I can work remotely, meaning there is no need for me to be in the country. On the flip side of that, surely if I’m earning their money, they’d prefer it if I spent it in their economy and their tax system?
