How to build a U.S. credit history as a worker on a visa?
Credit is important for many reasons. Establishing credit is an important step and should be no challenge for someone who already has good habits.  The same lessons and advice that you would find for a student to establish credit would be applicable to your case as well. Factors that influence credit score, Since you are already established in your home country (Australia), you probably have a credit card (and references) that you can provide for the first few challenges (renting a car, renting an apartment). Here are the steps, Your credit score should improve quickly as the first couple of credit cards and the installment loan show good payment history, low utilization, and gain some age. After 1-2 years, you should have a good score. When you start living in US, it doesn't actually matter what was your Credit history in another country. Your Credit History in US is tied to your SSN (Social Security Number), which will be awarded once you are in the country legally and apply for it. Getting an SSN also doesn't guarantee you nothing and you have to build your credit history slowly. Opening a Checking or Savings account will not help you in building a credit history. You need to have some type of Credit Account (credit card, car loan, mortgage etc.) linked to your SSN to start building your credit history. When you are new to US, you probably won't find any bank that will give you a Credit Card as you have no Credit history. One alternative is to apply for a secured credit card. A secured credit card is one you get by putting money or paying money to a bank and open a Credit Card against that money, thereby the bank can be secure that they won't lose any money. Once you have that, you can use that to build up your credit history slowly and once you have a good credit history and score, apply for regular Credit Card or apply for a car loan, mortgage etc. When I came to US 8 years ago, my Credit History was nothing, even though I had pretty good balance and credit history back in my country. I applied for secured credit card by paying $500 to a bank ( which got acquired by CapitalOne ), got it approved and used it for everything, for three years. I applied for other cards in the mean time but got rejected every time. Finally got approved for a regular credit card after three years and in one year added a mortgage and car loan, which helped me to get a decent score now. And Yes, a good Credit Score is important and essential for renting an apartment, leasing a car, getting a Credit Card etc.  but normally your employer can always arrange for an apartment given your situation or you need to share apartment with someone else. You can rent a car without and credit score, but need a valid US / International Drivers license and a Credit Card :-) Best option will be to open a secured credit card and start building your credit. When your wife and family arrives, they also will be assigned individual SSN and can start building their credit history themselves. Please keep in mind that Credit Score and Credit History is always individual here... 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.
If you are in the U.S., without credit cards, you probably don't have a credit history. Without a credit history, you won't be able to get a loan/mortgage, and even if you do, you'll get it on very unfavorable terms. Depending on where you live you might even have great difficulty renting an apartment. So, the most important reason to have credit cards is to have a good credit score. People have already listed other advantages of having credit cards, but another thing that wasn't mentioned is fraud protection. Credit cards are better protected against fraud than debit cards. You probably shouldn't use debit cards online unless you must. Also, without a credit card or credit history, some simple and important liberties like renting a car while you are travelling might be denied to you. So, in conclusion, it's bizarre, but in modern America you need credit cards, and you need them bad. "It all comes down to how the loan itself is structured and reported - the exact details of how they run the loan paperwork, and how/if they report the activity on the loan to one of the credit bureaus (and which one they report to).  It can go generally one of three ways: A) The loan company reports the status to a credit reporting agency on behalf of both the initiating borrower and the cosigner. In this scenario, both individuals get a new account on their credit report. Initially this will generally drop related credit scores somewhat (it's a ""hard pull"", new account with zero history, and increased debt), but over time this can have a positive effect on both people's credit rating. This is the typical scenario one might logically expect to be the norm, and it effects both parties credit just as if they were a sole signor for the loan. And as always, if the loan is not paid properly it will negatively effect both people's credit, and the owner of the loan can choose to come after either or both parties in whatever order they want. B) The loan company just runs the loan with one person, and only reports to a credit agency on one of you (probably the co-signor), leaving the other as just a backup. If you aren't paying close attention they may even arrange it where the initial party wanting to take the loan isn't even on most of the paperwork. This let the person trying to run the loan get something accepted that might not have been otherwise, or save some time, or was just an error. In this case it will have no effect on Person A's credit. We've had a number of question like this, and this isn't really a rare occurrence. Never assume people selling you things are necessarily accurate or honest - always verify. C) The loan company just doesn't report the loan at all to a credit agency, or does so incorrectly. They are under no obligation to report to credit agencies, it's strictly up to them. If you don't pay then they can report it as something ""in collections"". This isn't the typical way of doing business for most places, but some businesses still operate this way, including some places that advertise how doing business with them (paying them grossly inflated interest rates) will ""help build your credit"". Most advertising fraud goes unpunished. Note: Under all of the above scenarios, the loan can only effect the credit rating attached to the bureau it is reported to. If the loan is reported to Equifax, it will not help you with a TransUnion or Experian rating at all. Some loans report to multiple credit bureaus, but many don't bother, and credit bureaus don't automatically copy each other. It's important to remember that there isn't so much a thing as a singular ""consumer credit rating"", as there are ""consumer credit ratings"" - 3 of them, for most purposes, and they can vary widely depending on your reported histories. Also, if it is only a short-term loan of 3-6 months then it is unlikely to have a powerful impact on anyone's credit rating. Credit scores are formulas calibrated to care about long-term behavior, where 3 years of perfect credit history is still considered a short period of time and you will be deemed to have a significant risk of default without more data. So don't expect to qualify for a prime-rate mortgage because of a car loan that was paid off in a few months; it might be enough to give you a score if you don't have one, but don't expect much more. As always, please remember that taking out a loan just to improve credit is almost always a terrible idea. Unless you have a very specific reason with a carefully researched and well-vetted plan that means that it's very important you build credit in this specific way, you should generally focus on establishing credit in ways that don't actually cost you any money at all. Look for no fee credit cards that you pay in full each month, even if you have to start with credit-building secured card plans, and switch to cash-value no-fee rewards cards for a 1-3% if you operate your financial life in a way that this doesn't end up manipulating your purchasing decisions to cost you money. Words to the wise: ""Don't let the credit score tail wag the personal financial dog!""" Your credit score is really bad, and it's highly unlikely anyone will be willing to give you a mortgage, especially if you still have bad debt showing up on your credit report. What would help? Well, clearing off any bad debt would be a good place to start. Ideally, you want to get your credit rating up above 680, though that may be optimistic here. Note, though, that bad debt falls off your credit report after a while. Exactly how long depends on your province. Note that making partial payment, or even just acknowledging the debt, will reset the 'timer', however. I mention this, though, because you mention some of your debt is from 5 or 6 years ago. It may be just about to fall off. It would also help if you can show that your credit is so bad because of mistakes from a number of years ago, but you've been making payments and staying on top of all debts for the past few years, if that's the case. Also, it would help if you had a reasonable downpayment. 20% minimum, but you'll be a lower credit risk if you are able to put down 50 - 75%. You could also consider having someone with good credit co-sign the mortgage. Note that most people will not be willing to do this, as they take on substantial financial risk. All that said, there are some institutions which specialise in dealing with no credit or bad credit customers. You pay more fees and will pay a vastly higher interest rate, but this may be a good option for you. Check out mortgage brokers specialising in high-risk clients. You can also consider a rent-to-own, but almost all the advice I've ever seen say to avoid these if you can. One late payment and you may lose all the equity you think you've been building up. Note that things may be different if you are moving from the U.S. to Canada, and have no credit history in Canada. In that case, you may have no credit rather than bad credit. Most banks still won't offer you a mortgage in this case, but some lenders do target recent immigrants. Don't rule out renting. For many people, regardless of their credit rating, renting is a better option. The monthly payments may be lower, you don't need a downpayment, you don't have to pay realtor and legal fees (and pay again if you need to move). A couple of sites provide more information on how your credit rating affects your possibility of getting a mortgage, and how to get mortgages with bad credit: http://mortgages.ca/credit-score-needed-mortgage-canada/ and http://mortgages.ca/mortgage-solutions/new-to-canada-financing/, along with  http://www.ratehub.ca/mortgage-blog/2013/11/how-to-get-a-mortgage-with-bad-credit/ I'm not saying I don't like the idea of on-the-job training too, but you can't expect the company to do that. Training workers is not their job - they're building software. Perhaps educational systems in the U.S. (or their students) should worry a little about getting marketable skills in exchange for their massive investment in education, rather than getting out with thousands in student debt and then complaining that they aren't qualified to do anything. Agreed. I had a relatively fresh (five years old) Chap. 7 bankruptcy on my record when a potential employer ran a credit check prior to employment.   When I signed the form OKing the check, I told them what they'd find and said I was happy to explain it. I wrote a letter, they put it on file for the insurer (I needed to be bonded for this job -- I was co-signing six-figure checks) and it was fine. Other answers here cover some of the basics, but this is also a great time to start establishing a credit history and developing good financial habits to carry throughout your life. In addition to opening a free checking account with the local credit union, establish an overdraft line of credit on that account. Never close this account or this line of credit as it will work to increase the average age of your accounts when you apply for credit later in life. If you are disciplined with your use of credit cards, you may also want to apply for a low limit credit card through the same credit union for the same purpose as above. Never carry a balance on this card, but make minor purchases with it each month, never more than 20% of the balance, maybe just buy gas with it. Start tracking all of your spending and make a monthly budget. There are a lot of online tools that make this very easy. Establishing the habit now will help you make informed financial decisions in the future. Open a Roth IRA and put at least 10% of your money away for retirement. In the future your income may increase enough to put you in the 25% tax bracket. If that ever happens, open a Regular IRA and put the money there instead. Also when you have employers that offer 401k matching do the same thing with a Roth 401k account. Keep your money invested in a low cost index fund. No, don't open a credit card. Get used to paying cash for everything from the beginning. The best situation you can be in is not to have any credit. When it comes time to buy a house, put down %30 percent and your 0 credit score won't matter. This will keep you within your means, and, with governments gathering more and more data, help preserve your anonimity. 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.
