This is completely incorrect. When a resident naturalizes in the US, they renounce allegiance to other countries, but this is not renouncing citizenship...totally different concepts. The US absolutely DOES recognize dual citizenship provided the other country does as well. There are thousands if not tens of thousands of dual citizens here including myself, and many of us carry two passports.
The only way to lose US citizenship if you're American born is to formally renounce it. The only way to lose US citizenship if you're foreign born (naturalized) is to be found to have lied on your naturalization application, or failing that, formally renounce it.
