Romulo Castro considered attending his asylum interview in Rosedale, Queens, dressed as Fidela Castro, a towering drag queen in six-inch stilettos, a bright green poodle skirt and a mane of strawberry blond hair. In the end, Mr. Castro, 34, opted for what he described as understatement: pink eye shadow, a bright pink V-neck shirt and intermittent outbursts of tears.

After years of trying to conceal his sexual orientation back home in Brazil (where Fidela never made an appearance), Mr. Castro had been advised by his immigration lawyer that flaunting it was now his best weapon against deportation.

“I was persecuted for being fruity, a boy-girl, a fatso, a faggot  I felt like a monster,” said Mr. Castro, who reported being raped by an uncle at age 12, sexually abused by two police officers, and hounded and beaten by his peers before fleeing to the United States in 2000. “Here, being gay was my salvation. So I knew I had to put on the performance of my life.”

Amid international outcry over news of the Czech Republic’s testing the veracity of claims of purportedly gay asylum seekers by attaching genital cuffs to monitor their arousal while they watched pornography, some gay refugees and their advocates in New York are complaining that they can be penalized for not outwardly expressing their sexuality. While asylum-seekers and rights groups here expressed relief that use of the so-called erotic lie detector is impossible to imagine in the United States, some lamented in recent interviews that here too, homosexuals seeking asylum may risk being dismissed as not being gay enough.
