Are credit histories/scores international?
Currently the credit history are not International but are local. Many countries don't have a concept of credit history yet.   Having said that, if you are moving to US, depending on your history in your country, you can ask the same bank to provide you with a card and then start building history. For example in India I had a card with Citi Bank and when I moved to US for a short period, I was given a card based on my India Card, with equivalent credit in USD. If you are moving often internationally, it would make sense to Bank with a leading bank that provide services in geographies of your interest [Citi, HSBC, etc] and then in a new country approach these institutions to get you some starting credit for you to build a history. "It's not just that credit history is local; it's that it's a private business run for profit. The ""big three"" credit bureaus in the US are Experian, Equifax and Transunion.  They collect information on debt usage and abuse from various companies in the US, and charge a fee to provide that information (and their judgement of you) to companies interested in offering you further credit.  But there's nothing stopping a company from collecting international credit histories, or specialized credit histories either (for instance, there's a company called ChexSystems which focuses on retail purchase financing (mostly auto) and checking account abuse, while ignoring other types of lending). That being said, I don't know of any companies which currently collect international credit histories.  Perhaps in Europe, with more nations in close geographic proximity, there would be, but not in North America." Credit history is local, so when you move to the US you start with the blank slate. Credit history length is a huge factor, so in the first year expect that nobody would trust you and you may be refused credit or asked for deposits. I was asked for deposits at cell phone company and refused for store cards couple of times. My advice - get a secured credit card (that means you put certain sum of money as a deposit in the bank and you get credit equal to that sum of money) and if you have something like a car loan that helps too (of course, you shouldn't buy a car just for that ;) but if you're buying anyway, just know it's not only hurting but also helping when you pay). Once you have a year or two of the history and you've kept with all the payments, you credit score would be OK and everybody would be happy to work with you. In 4-5 years you can have excellent credit record if you pay on time and don't do anything bad. If you are working it the US, a lot of help at first would be to take a letter from your company on an official letterhead saying that you are employed by this and that company and are getting salary of this and that. That can serve as an assurance for some merchants that otherwise would be reluctant to work with you because of the absence of credit history. If you have any assets overseas, especially if they are held in a branch of international bank in US dollars, that could help too. In general, don't count too much on credit for first 1-2 years (though you'd probably could get a car loan, for example, but rates would be exorbitant - easily 10 percentage points higher than with good credit), but it will get better soon. Some countries in European Union are starting to implement credit history sharing, for example now history from polish bureau BIK and German Schufa are mutually available. Similar agreements are planned between polish BIK and bureaus in the Netherlands and United Kingdom.
"Your total debt is equal to your total non-credit debt (student loans, car loans) + your total available credit.   This is the truth of the ""low balance"" fear from lenders that you had heard about. Your credit utilization is across all of your cards.   So if you have two cards, both with 15K limits and one is maxed out and one is empty, that is 50% utilization.   If you have both cards with 7.5K balances, that is also 50% utilization. For the 8 cards that are paid off and still open, after you buy a house, I'd close any cards you aren't using.  Not everyone will agree with this. If possible, I would close the 8 cards now and pay off the 15K balance before buying a house.  If it's hard to pay it off now, it will be harder when you have a mortgage and home maintenance costs. If you want to buy the house before you pay off all of your credit card debt, I'd still close the 8 cards that are already paid off and pay down your last card to 4K (or less) to get under 25% utilization. The credit rating bureaus do not publish exactly how a different utilization rate of credit will affect your score, but it is known that lower utilization will improve your score.  FICO calls this ""Proportion of credit lines used (proportion of balances to total credit limits on certain types of revolving accounts)"" Also, the longevity of your credit history is based on type of account (credit cards, car loans, etc.) so if you keep one credit card open, you still keep your long ""history"" with credit cards on your credit report.  FICO calls this ""Time since accounts opened, by specific type of account""" "When I was in high school, my mom got me a joint credit account with both of our names on it for exactly this reason. Well, that, and to have in case I found myself in some sort emergency, but it was mostly to build credit history. That account is still on my credit report (it's my oldest by a few years), and looking at the age of it, I was 17 at the time we opened it (and I think my younger sister got one around the same time).  In my case, I now have an ""excellent"" credit score and my weakest area is the age of my accounts, so having that old account definitely helps me. I don't think I've really taken advantage of it, and I'm not sure if I'd really be worse off if my mom hadn't done that, but it certainly hasn't hurt. And I plan on buying a house in the next year or so, so having anything to bump up the credit score seems like a good thing." The SCHUFA in Germany works a bit different from the FICO score in the US. My background: I am a German currently living in the US. The information others want to see from the SCHUFA are a bit different. If you want to example rent a house or an apartment, the landlord often wants to see a SCHUFA statement which only shows that there are no negative entries. This statement you can get easily from online and they don't mention your credit score there. If you apply for a real credit or want to lease a car, they want to look deeper in your SCHUFA profile. However, very important is: They need signed permission to do this. Every participating company can submit entries to your profile where the score is calculated from. For example mobile phone plans, leasing a car, applying for a loan. Some lenders decide on the score itself, some on the overall profile and some also take your income into account. Since there is no hire & fire in Germany you are often asked to show your last 3 paychecks. This, in combination with your SCHUFA score is used for determination if you are eligible for a loan or not. However, they check through every entry which is made there and as long as it is reasonable and fits to your income (car for 800 EUR/month with a 1000 EUR salary does not!) you should not have a problem establishing a good score. The, in my eyes, unfair part about Schufa is that they take your zip code and your neighborhood into account when calculating their score. Also moving often affects the score negatively. To finally answer your question: Credit history is also built by mobile phone plans etc. in Germany. As long as you pay everything on time you should be fine. A bad score can definitely hurt you, but it is not as important to have a score as it is in the US because the banks also determine your creditworthiness based on your monthly income and your spending behavior. Since we seem to be discussing credit score and credit history interchangeably, if I can add credit report as the third part of the puzzle, I have another point. Your credit score and credit report can be effective tools to notice identity theft or fraud in your name.   Keeping track of your report will allow you to not only protect your good name (which is apparently in dispute here) but also those businesses who ultimately end up paying for the stolen goods or services. In the US, money talks and bullshit walks. You can skip any credit history requirement if you demonstrate your ability to pay in a very obvious way. Credit history is just a standardized way of weeding out people that cannot reliably pay, instead of having to listen to an individual's excuses about how the bank overdrafted their account five times while they were waiting for their friend to pay them back for bubble gum. If you can show up with a wad of cash, you can get the car, or the apartment, or the bank account without the troubles of everyone else.  But you can begin building credit with a secured credit card pretty easily. This will be useful for things like utilities and sometimes jobs. Also, banks won't be opposed to giving you credit if you have a lot of money in an account with them. You should be able to maintain an exemption from all socioeconomic problems in the United States, solely due to your experience with money and assets. 12% is ridiculously high and routine for loans with no credit history, esp. from the dealer. I don't think though paying off would hurt your credit - you've already got installment loan on your report, and you have history of payments, so it shouldn't matter how long the history is (warning: this is kind of guesswork compiled from personal experience and stuff read on the net, since officially how credit score calculated is Top Secret).  If you have the loan and credit card with good payments, only thing you need to build credit is time (and, of course, keeping everything nicely paid). Of course, if you could find a loan with lower rate somewhere it's be great to refinance but with low credit you would probably not get the best rates from anywhere, unfortunately. You really can't. Credit rating is determined by financial history, and until your kids are old enough to legally sign a contract they have essentially no financial history. Interesting out-of-the-box thought, but not workable. Is it possible for the card issuing banks to check my score without my permission? As far as I understand these things, that is exactly the whole purpose of these sorts of credit-rating institutions. The banks and other financial businesses are their customers. They exist to serve those customers. Their relationship, if any, with a consumer is probably secondary to that. When you apply for credit, you give that business any permission needed.
