The State Department announced Americans applying for a passport will be allowed to choose "X" as a gender option starting April 11. 

"We're setting a precedent as the first US federal government agency to offer the 'X' gender marker on an identity document," said Douglass Benning, principal deputy assistant secretary for consular affairs at the State Department, according to CBS News. The announcement comes on International Transgender Day of Visibility.

The "X" gender option will be open to all applicants, despite the gender specified on their birth certificate or on other legal documents. 

The State Department consulted with other countries, including Canada, New Zealand, and Australia, who have also added the "X" gender option, CBS News reported.

"The provision of an 'X' gender marker option is important because human beings do not always fit within a male or female category around the world, the lived realities of transgender intersex, non-binary and gender-nonconforming persons reflects that there is a wider spectrum of humanity than is represented by a binary sex designation on passports," said Jessica Stern, U.S. Special Envoy to Advance the Human Rights of Lesbian, Gay, Bisexual, Transgender, Queer and Intersex (LGBTQI+) Persons, to CBS.
