Everything said is correct but it takes a lot of work and I can't see a UK company doing that unless it is a super specialised role that they simply cannot fill in the UK. To set up entity or DBA in the US might be 2 hours but they then have to pay someone to do your payroll/taxes each month and to make sure they are following US laws etc. I was employed this way but in reverse for several years. I know someone doing this now (also in reverse) and the 3rd party company charges $900 USD a month to do this for one employee. That's 900 USD just to make sure the taxes are correct and all laws are followed. As far as contractor, the rules are tightening (google IR35) and so companies will struggle to get away with paying you as a contractor unless the role/work is truly contractor work. To your original question for a visa - again that would be next to impossible unless the role is super specialised and they can say that there is no one qualified to do the role in the UK that they can find.

Hi! Yes, absolutely. You shouldn't need a work permit or a visa unless you are needing one for the US portion of the role. The UK company can bill you in two ways: as a contractor or as an employee. If you are an employee they will need to have a US entity that covers the legal regulations and taxes. If you are a contractor, you will be responsible for your taxes and they will send you a tax form reporting your earnings at the end of the year. All of these elements are the responsibility of the company to define
