Landlord, bring a credit card that can pay US dollars! The United States and China are different! There are many hotels, so you have to show your credit card when you check in. There are also many car rental agencies and other rental businesses, which need to show credit cards. Cash is useless here! Because it is illegal for some States in the United States to accept pledges, people can only register your credit card information! Sometimes you even need a credit card to travel by train, because those places don't accept cash!

It can be said that in America, there are three major documents. If you don't have them, you will definitely be unable to move! First ID card, second driver's license and third credit card! There are three things you must have! Of course, for foreign tourists, you have to carry your passport with you! Because many times you are walking on the road, suddenly a police car will stop next to you, and then the police will get off and let you show your ID!
