Plans to move to UK, no clue where to start.

The biometrics are part of the visa application. Don't worry -- when you get that far, the application process will tell you what you have to do.

You have a lot to do before then 

Sorry, didn't edit fast enough. Was just asking what a biometrics are and how to go about completing them. Should be the last question. Many more thanks to those helpin me.

After you have submitted and paid for a visa application, you are required to book a biometrics appointment, whereby you go to a biometrics processing centre and they take your photograph and fingerprints. You cannot get biometrics completed until after you have applied for a visa and once the biometrics have been done, you have 14 days to submit your visa application paperwork to the embassy.

If you are not planning to apply for a visa just yet, then you do not need to worry about biometrics.... this will be something you will need to do a few months down the line when you are applying for an actual visa.

Biometrics are digital fingerprint and eye scans.  They are taken after a visa application is submitted and the fee paid.  Once you've done those things, you will be prompted to make an appointment at a local biometrics facility.  

x-posted with Stoatula and ksand24--and agree with both of them.  Biometrics are the last things you should be thinking of at the moment 

Biometrics are where fingerprints and photos are taken, and then they are electronically sent to the consulate where you have to send your documents to. When you fill out your application online, they'll ask you to schedule biometrics and give you the closest locations to you, so you can choose where and when to go get them done, then after that you have 14 days to submit your documents to the consulate to complete your application.

Edit: wow, beaten to the punch slightly

Heh. I'm a refresh-monkey tonight. Banging around the internet and I'm BORED 

And who exactly do I contact for a visa? Once I figure out what I'm doin, of course. I live in Ohio, I know the post office handles passports but unsure about visas.

www.visa4uk.fco.gov.uk

The forms are all online now, you don't actually contact anyone, just sign on and fill in the form.

ETA:  Yes!  This time I win the super ninja posting race! (don't mind me, I'm a bit overtired  )

You fill out an online form initially for your visa from http://www.visa4uk.fco.gov.uk. It'll take you through all the questions you need to answer, collect your money, and then schedule your biometrics which is your next step.

Edit: I'm bored like Stoatula, hence why I keep cross posting with everyone

Visas for foreign countries are handled by the consulates/embassies of those countries rather than the US gov't (so no post office):
http://ukinusa.fco.gov.uk/en/visas/ is the UK embassy in the US website
online application here: www.visa4uk.fco.gov.uk

Wow.. I know this is none of my business, but have you met this girl in person before?  Have you traveled to the UK and spent any amount of time there?  I would HIGHLY recommend slowing down your plans a bit if you have not done both of these things.  

But with that being said, there is no office to go to to apply for the visa.  It is done  online and then mailed off. You will need to do a lot of research beforehand as there is no one who tells you step by step what to do in a super clear fashion (unless you hire someone that is).

Just don't be too hasty about the visa process - it's not quite as easy as just filling out a form. First, you have to research the different visa options and decide which one applies to you.

Then, as most of the people here can tell you, a visa application can take several weeks/months of careful planning before you are ready to fill out the form, including: collection of required documents - bank statements, passport(s), birth certificate(s), CVs/resumes, tenancy/rental agreements for accommodation, living expenses budgets, proof of relationship etc.

Thanks everyone. I'll be back if I stumble across any problems.
I've never been to the UK but I don't see how it can be any worse than Cleveland lol. I gotta go to school either way, I heard medical and education is free in the UK. I'm going to assume that's only with citizenship though, which kind of voids my plan of going to school after achieving citizenship. Do you guys think it'd be easier for her to become a citizen of the US, do you know anything about that process or is it pretty much the same?

And yeah it does seem like we're movin pretty hastily, and I thank you for the concern and interest of my well-being but it's pretty serious and I think I got it under control. If things go awry that'll be my problem.

Healthcare is free, higher education is not and hasn't been for many years.

Definitely easier to go US to UK, shorter too, particularly if you marry a UK citizen.  But as a foreign student you would be paying some pretty hefty fees.  It's going to be expensive no matter what, that's the b*tch of international relationships, I'm afraid.

Higher education is not free at all - it used to be about 20 years ago, but for UK students, fees are £3,000 per year (about $5,000 a year). You cannot qualify for these low fees until you have been legally living in the UK for at least 3 years. So, if you were to get a student visa or study on a spousal visa before 3 years are up, you would have to pay international fees and it would cost you around £10,000 per year (about $15,000 a year) to study in the UK.
