1 U.S. Code § 7 - Marriage
“(a)For the purposes of any Federal law, rule, or regulation in which marital status is a factor, an individual shall be considered married if that individual’s marriage is between 2 individuals and is valid in the State where the marriage was entered into or, in the case of a marriage entered into outside any State, if the marriage is between 2 individuals and is valid in the place where entered into and the marriage could have been entered into in a State.”
Can you find a literate 10 year old to read that to you?
