Question: do people becoming naturalized citizens have to renounce their citizenship to their home country?
AFAIK, only the foreign country can renounce the citizenship of one of its citizens.
The new naturalized citizen probably has to go to the foreign consulate and say "I no longer want to be a citizen of (fill in the blank). Then they go through that country's legal means of renouncement.
The statutes require that naturalized citizens must take an oath that renounces loyalties to foreign states, but in practice, dual citizenship is increasingly tolerated. The taking of an oath of military service or public office in a foreign country may raise problems at the margins, but even that is increasingly tolerated.

Yes I had to so when I went for my final interview one month before the ceremony...I raised my right hand and swore that I renounced my current citizenship...
and I came from an ally, a British country, New Zealand, and not a 3rd world one ...
It is part of the naturalization process...I had no choice if I wished to become an American citizen...I could not be both...
for those 30 odd days my new Zealand passport was no longer recognized by the US or any other country, and I could not leave the US because I no longer had a valid passport...
as soon as I went through the ceremony, I was eligible to apply for a US passport...
