How much is the income of American customs civil servants?

The annual salary of customs declarers is 4-6W. If you follow upstairs, you can get 18W a year, almost catching up with the doctor, but don't pretend to understand. Customs is a government department, so when you are a customs officer, the government will buy you medical insurance and accident insurance. In the United States, these funds cost about 4 thousand a year, and after the government retires, the pension is also relatively high. This is the advantage of being a customs officer, government work and an iron rice bowl. thank you
