It’s unclear whether Snowden swore the oath of allegiance at the same time as he was granted a passport, but the two are common procedures when foreigners become Russian citizens. The text includes swearing “to protect the freedom and independence of the Russian Federation, to be loyal to Russia, to respect its culture, history and traditions,” and to promise to “perform the duties of a citizen of the Russian Federation for the good of the state and society.”
Snowden has already broken his oath to the United States Constitution…so this oath must be really sincere.
