The Trump administration is denying visas to the same-sex partners of foreign diplomats, unless they get married by the end of the year.
If not, then they will have to leave the USA.
However, many of the diplomats come from countries where same-sex marriage is illegal, and they could face persecution upon returning to their home country.
Some countries allow civil partnerships, but being in a civil partnership would not qualify a person for a US visa.
This reverses a 2009 order by the former secretary of state, Hillary Clinton, which granted visas to same-sex partners of diplomats, regardless of their marriage status.
“This is an unconscionable, needless attack on some LGBTQ diplomats from around the world, and it reflects the hostility of the Trump-Pence administration toward LGBTQ people,” said David Stacy of the Human Rights Campaign which also called the move “unnecessary, mean-spirited and unacceptable”.
