The scenario which shikarishambu may have been implying and I would be interested to find out too is if you are (or will be) a dual citizen.
After the oath ceremony and before receiving your US passport, can you use your foreign passport to leave the US (and enter your home country)? You could then get someone to mail or bring over your US passport once it is processed and use it to reenter the US. I know it is a legal requirement to enter the US using a US passport if you are a US citizen, but does this apply to leaving the country?
Same day processing might be an option but getting to a passport agency isn't easy if you live right in the center of the US (they are mostly on the west and east coasts

).
