The basic unit of currency in the United States is the dollar.
Coins make up denominations smaller than the dollar.
It is neither practical nor safe to carry large amounts of cash. Upon arrival in the U.S., you should open a bank account as soon as possible. Each bank in the Middletown area has its own policies on types of accounts offered, service charges, minimum balance requirements and interest yields. To open an account, you will need to provide identification to the bank. Ask the teller for a W9 form, which you should fill out.
