Question: is polygamy legal in the united states today

Answer: No, Polygamy is the act or condition of a person marrying another person while still being lawfully married to another spouse. As this is the very definition of bigamy, it is illegal in the United States. The crime is punishable by a fine, imprisonment, or both, according to the law of the individual state and the circumstances of the offense. Polygamy was outlawed federally by the Edmunds Act, and there are laws against the practice in all 50 states, as well as the District of Columbia, Guam, and Puerto Rico. Because state laws exist, polygamy is not actively prosecuted at the federal level, but the practice is considered ``against public policy'' and, accordingly, the U.S. government won't recognize bigamous marriages for immigration purposes (that is, would not allow one of the spouses to petition for immigration benefits for the other), even if they are legal in the country where bigamous marriage was celebrated. Any immigrant who is coming to the United States to practice polygamy is inadmissible.
