You basically have four options if you want to work here:

1) Find some British or EU ancestry, obtain passport, work in Britain as your British/EU citizenship gives you the right to.

2) Find someone with British or EU citizenship, fall in love with them, get married and go through all the time-consuming hoops to obtain said right to work in the UK.

3) Possibly the hardest option is to do what you're wanting to do, obtain a Tier 2 visa. Unfortunately you've come of age in an era when immigration to the UK by non-EU citizens is harder than at any time previously due to vitriolic anti-immigration rhetoric in the media and politics and concerns about the number of immigrants coming here. The relevant visa for you is a Tier 2 visa, which is a visa for skilled workers who don't have the right to work in the UK.

Unfortunately these Tier 2 visas are capped at 20,000 a year and can only be requested by employers which are approved by the Home Office - typically either very specialised employers or large multinationals. Generally to obtain a Tier 2 you need to be a) very skilled at what you do and b) skilled at something that is so scarcely found that we can't find someone from the EU to do it.

Regular skills shortage lists are published by the Home Office but unfortunately the arts professions such as journalism don't tend to feature on there as there are often many UK and EU journalists struggling to find work.

We generally suggest on here either coming to study in the UK (say, a postgraduate) which would get you over here in the short term - and who knows who you might meet? It could end up in a job offer, a relationship, whatever. It's very tricky, but it is doable.

4) Failing that it would be a case of landing a job with a large American company that has offices in the UK and getting an intra-company transfer visa, although these are time-limited.
