For children who are going to study abroad, I suggest that parents apply for a credit card for your child in advance. You can choose to open a credit card in the name of your child, or you can choose to apply for a master card and a payment card. You keep the main card and pay the card to the child. In this way, you can check your child's consumption at any time so that you can remit money to him in time. Because according to the regulations of the State Administration of Foreign Exchange, the cash limit for a person to take foreign exchange out of the country cannot exceed the equivalent foreign currency of 5,000 US dollars. In fact, the use of credit cards is becoming more and more common in the United States. Whether you are shopping or traveling to a restaurant, you can pay in advance by credit card. In this way, whether you want to pay the tuition deposit in advance in China or you just arrived abroad and can't open a local bank account, you can pay by credit card first, which is convenient and fast.
