Thank you for you concern over my life. YES I HAVE A VISA. I would love to talk about things to do in Southern England over something that has nothing to do with the question I asked. I can't I can't.
Immigration rules have tightened significantly over recent years because of abuse of the immigration rules (not saying you are abusing them, just in general abuse has happened).
This means that many people now fall foul unintentionally. A visitor visa (stamp at the airport or applied for in advance) does not allow any type of work, even remote working. It catches a lot of people out. If you ever tried to come to the UK and it transpires you fell foul of the rules (bank statements showing payment, email history etc...) could leave you upset, confused and with a ban. It would hurt your immigration records to other countries to.
I think Larabee is just trying to make sure you don't harm your immigration record, even if it was only because you didn't know the rules (and let's face it, one doesn't tend to know the rules unless you do masses of research. I haven't a clue of US rules!!!).
Not sure if you're aware, but your post in response to possibly helpful information is really rude by British standards (not sure about American ones...). Comes off as quite childish, which again leads me to believe you might be working illegally.... because of ignorance to the rules. So now you aren't ignorant, and you can make an informed choice about YOUR LIFE. Do with this information what you will.
