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 U. S. currency.
Your Bank
    In many cases you can purchase U. S. 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 U. S. currency either before you board your flight or at the U. S. airport on arrival Note that U. S. airports typically have fewer currency exchange counters than travelers are accustomed to seeing in other parts of the world. If the air-port you are flying into is not in a major U. S. 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.

    Sometimes the biggest problem you have at work is your own stress (压力). To reduce stress at work, you can come early to the workplace and give yourself time to lower your stress level before meetings or telephone calls. Prepare for stressful situations. If all the above fails, find a quiet plate to think, read, or calm down. Another way to reduce stress is to set goals that can be achieved. Know your limits and be well-prepared.
