Am I being scammed somehow in being persuaded to move to another country?

It strikes me that the most likely thing here is that you’re being baited for some kind of advance-fee scam or an airline fee scam. The classic signs are all here; exotic locale, once-in-a-lifetime-offer that seems too good to be true, other person is willing to invest considerable expense without you having to risk anything, etc, etc.

Given that they’re offering you the equivalent of about $15,000 of accommodation and services, if you want to assess whether they’re actually genuine, you could ask them to advance you a very small sum of money (say, $100) toward a new piece of equipment for your youtube videos. Scammers hate paper trails and they hate risking their own money. If they’re legitimately going to act as your agent they’ll send the money without question from their bank account to yours. If they hmm and hah, insist on paying via an anonymous method (such as Western Union), threaten to break off contact because of your unreasonable request or seem in the least anxious about spending that kind of money then you know that they’re definitely trying to scam you.

My guess is that at some point over the next few weeks/months they’ll claim that they’ve sorted out your accommodation (so that there’s a ticking clock to raise the stakes) and they’re ready to book your travel but they’ve found out that they need your personal details (so you’ll need to post your passport, etc) to make the bookings. They may also ask for you to pay a portion of the travel fees or some kind of “arrangement fee” that “has to come from your account, not mine”.

If the other answers and comments on this question haven’t put you off pursuing this further, you should:

• Do some thorough research into UK immigration and employment law as it would apply to you – depending on your nationality, etc. As a starting point you can find information on the UK government website and possibly on the Expatriates or Law SE sites.
• Ask your contact any questions arising from this. For example are they offering to sponsor your visa application, can they send you a copy of the employment contract they will be offering you, and so on.
• Check their answers by getting independent legal advice. For example, have a lawyer examine the employment contract and review what your immigration/visa situation would be.

If your contact is not willing to cooperate with this, I suggest that would be a red flag that it is a scam. If you think the above steps are too difficult or expensive, I suggest that the risk that it is a scam is too big for you to take.

You need to get an understanding of this individual outside of the communication channels he is controlling. It is easier to get assurance about an individual’s real reputation on some social media than on others. YouTube is overrun with trolls, Twitter is a little bit better – you can understand people’s history and network a bit more easily, Facebook is slightly better again – you can usually separate bots from real people fairly easily, LinkedIn is much better just for understanding people’s careers and bona fides.

Do they have a blog, or company sites they happy to show you? Do they work with well known people who are happy to vouch for them?

Email or message them: make sure you ask them all the questions you want answered. It’s okay to say that you want to be clear about your immigration/visa/employment status. If they are offering you a job they should be happy to offer you a written employment contract.

If you can’t build up a clear picture of who this individual is then just don’t trust them. If they are trustworthy they will also be transparent.

Have you had a Skype or Hangouts chat with him? Gotten to know him? Searched up his name and found his face or info somewhere? Really, if you’re going to become business partners, it’s ridiculous to fly somewhere without having seen and done some research on each other, and this is true regardless of whether or not this is a scam.

Try doing these. If he gives you a hard time, it’s probably a scam. Otherwise, maybe not (unlikely).

This person has offered to pay for me to go to the UK and pay for my accommodation, food, internet, everything, and give me a year to start making money from it on my own. I don’t know much about it since it all came out of nowhere, but he’s saying I can get famous and has never seen anyone grow like this. Saying I can make lots of money and wants to help me get there.

Even if you assume for a minute that this person has no ill intentions it is blatantly obvious that this person wants you to move for his gain, most obviously financial.

Always Remember: if you’re getting it for free, you are not the customer you’re the product.

And you actually are the product that he is willing to sell even in the best possible case. Since you do have talent and your creations can become famous, start learning how you can continue to grow your fan base yourself. The same YouTube that made you famous will have tons of videos to help you with that.

I like the other answer but I think the suggestion it contains and the discussion on it is going overboard with an investigative theme when this is only a matter of due diligence as of now. What should the OP do if the other person is reported clean after a casual contact with police? Just because someone is not known to the police or because they aren’t able to furnish that information easily what should the OP do? Consider the other person clean and run for the deal? That’s risky.

It’s not really a matter of investigation, small business deals don’t work that way. OP should stay away from such a deal regardless of what comes out from law enforcement.

Even in the best case scenario this deal makes no business sense.

“This doesn’t really answer the question” but it is important enough to ensure it gets noticed! (If moderators disagree, they can “fix it.”)

Sex trafficking and other forms of slavery are real and widespread. While it seems to me that no one would spend that much time and effort to get a victim, one never knows.

I recommend, without this person’s knowledge, that you contact law enforcement in the area he claims to be in and/or wants to meet you in, and ask them whether they think it is legitimate.
