INDIANAPOLIS (AP) — A transgender man granted asylum by the U.S. last year is challenging an Indiana law that prevents him from changing his first name to a male name that matches his gender identity.

The 31-year-old, who was brought to Indiana from Mexico illegally by his parents at age six, contends in his federal lawsuit that Indiana’s law requiring anyone seeking a name-change to provide proof of U.S. citizenship is unconstitutional and essentially forces him to “out” himself as transgender whenever he must display his driver’s license.

That law was passed in 2010 amid what his attorneys say was a spate of “anti-immigrant lawmaking” in several states.
