Another reason that federal jobs are not available to people who are not U.S. citizens is that Americans want their taxes (or money that they pay to the government) to be used to pay other Americans and not people from other countries.
另一個非美國公民不能申請聯邦職位的原因是美國人希望他們的稅款(或支付給政府的錢)用在別的美國人而不是別國人的身上。
U.S. citizens may run for office (or try to get elected (or chosen) for a political job by voters).
美國公民可以競選公職(或努力獲得選民選舉的政治職位。)
This can be anything from the mayor (or elected leader) of a city to the president of the United States and every job in between.
無論是一市之長還是美國總統等任何職位都包括在內。
Often there are other requirements to run for office, such as age or residency (or the amount of time that someone has lived in a certain place).
競選公職通常還有其他要求,例如年齡或居住年限(或某人居住在某地的時間)。
Finally, only U.S. citizens can carry (or have and travel with) a U.S. passport.
最后,只有美國公民才能持有(或擁有并帶著去旅行的)護照。
Not all citizens have a passport.
不是所有公民都有護照。
It is a document that we must apply for (or fill out a form to request).
它是我們必須要申請(或填一張申請表)的文件。
But all Americans are entitled (or have the right) to get a passport and travel to other countries.
不過所有美國人都可以(或有權)獲得護照并去他國旅行。
People who are not U.S. citizens, of course, cannot have a U.S. passport.
非美國公民的人當然不能持有美國護照。
