单选题 The practice of exchanging foreign currency can vary by country. In one country, you may have to change your money at the airport, and in other countries you may need to buy your foreign currency in advance. Here are some places you can exchange foreign currency for US currency.
Your Bank
In many cases you can purchase US currency for your trip from a bank. Banks tend to have higher exchange rates than some currency exchange businesses. Before you purchase currency from a bank, check the currency change rates for that day so you can compare the rate the bank is giving and determine if it"s a good offer. There is a fee involved in withdrawing foreign currency from your bank.
The Airport
Currency exchange businesses can be found at most international airports, so you can purchase US currency either before you board your flight or at the US airport on arrival. Note that US airports typically have fewer currency exchange counters than travelers are accustomed to seeing in other parts of the world. If the airport you are flying into is not in a major US city, consider using the exchange service in your departure airport to be on the safe side. If you are in an airport where several exchange companies operate, be sure to shop around for the best rate and lowest exchange fee.
