Having a good credit score in the U.S. is important for everyday life - to get a postpaid mobile phone plan, rent a house, get insurance, buy a car, and sometimes even apply for a job! If you do not have a good U.S. credit score, you may have to pay a high-security deposit to access these services - for example, your landlord or your insurance company may ask you to pay a security deposit as high as $1,500. Sometimes, you may even be denied access to these services, if you do not have a credit score. Having a good credit score could also help you get more financial opportunities in the future, including lower interest rates and higher loan amounts.
