If you work for the post office, you're a civil servant. The Civil Rights movement focused on the notion that all American citizens were entitled to the same basic civil liberties.
There is also time limit to consider for sending the amended returns, and it is generally three years from the time you filed the returns or two years after the tax payment (whichever is later). If you plan to amend more than one tax return, you have to file separate 1040X for every one you want to change.
However, it may take 8 to 12 weeks or longer to process the return. If 8 weeks have elapsed and you have not received your refund, call (800) 829-1040. That takes care of your federal tax refund. Almost all states that have an income tax also have a web-based form for checking the refund status.
