Oscar Cantua was one of 5100 graduates at the University of Texas at San Antonio鈥檚 2019 Spring Commencement. He received an undergraduate degree in physics. It stemmed from an early interest in black holes. But his path to graduation was a rocky one. Oscar, his mother and his older sister left Mexico when he was only five.
鈥淪he鈥檚 been working factory jobs, very manual labor jobs since she was a young girl,鈥 Cantua said. 鈥淪he wanted us to have an opportunity to have higher paying jobs, jobs that wouldn鈥檛 require us to be on our feet 24/7.鈥
The family ended up in Sinton, Texas, about 26 miles north of Corpus Christi. They stayed with a family friend.
鈥淚 came in the middle of the school year, but fortunately I had been going to a bilingual school in Mexico, so I was able to communicate with all the kids,鈥 Cantua said. 鈥淭he majority of my school were actually of some sort of Hispanic, Latino origin, so I was able to make friends pretty quickly, especially being [the] new kid and being able to talk in Spanish, being from Mexico. It was certainly easier than it could have been.鈥
Cantua is a U.S. citizen through his father, who was born in Oakland, Calif. His mother and sister are Mexican citizens. Cantua鈥檚 sister is about seven years older, and her father died before Cantua was born.

Cantua says his mother鈥檚 deportation came out of the blue, just as he finished his sophomore year. He and his mother had made a trip to Corpus Christi to find him a laptop.
鈥淥n the way back, we were about to turn into the road that my house was on,鈥 he said. 鈥淪he ended up getting into the turning lane without signaling. Immediately we saw cop lights.鈥
Cantua said his mother was nervous 鈥 she didn鈥檛 know much English, and Cantua was translating for her.
鈥淚 don鈥檛 know if he didn鈥檛 like that," he recalled, "but he asked her to step out of the vehicle and ordered me to stay inside. I didn鈥檛 know what was happening until he was putting her in handcuffs for some reason.鈥
Cantua鈥檚 sister decided to return to Mexico after she graduated from high school.
鈥淪he was trying to go to college, but we didn鈥檛 have the money,鈥 said Cantua. 鈥淒ACA came into effect literally the year after she graduated, so she decided to just go back to Mexico with her family.鈥

Instead of following his family back across the border, Cantua made the decision to stay in Sinton and finish school. His father, who lives in McAllen, offered to take him in.
鈥淏ut...I was so used to Sinton and had built up a decent reputation in the school,鈥 Cantua said. 鈥淚 had a lot of extracurriculars. So there [were] a lot of things I would have had to sacrifice in order to move somewhere else.鈥
Cantua鈥檚 fascination with black holes began in sixth grade. He knew by middle school he would major in physics, but Cantua would have to find a way to leap the financial hurdle to get to college.
He applied for the at the University of Texas at San Antonio. It鈥檚 a merit-based four-year scholarship that includes tuition, fees, room & board, and auto-enrollment in an honors program. He got the scholarship and found himself under the mentorship of Eric Schlegel, Vaughan Family Professor of Physics & Astronomy at UTSA. Schlegel gained fame for the discovery a in 2016. Schlegel put Cantua on a path to a future career in academia in astrophysics and research.
Cantua says his mother, like most mom鈥檚, worries whether he can make a living, but mostly wants him to be happy.
鈥淪he always worries. 鈥業s there actually money in this? Are you going to be starving?鈥 I tell her no. It might take a while but it鈥檚 a comfortable life. Even if I get paid on one of the lower ends, that鈥檚 a lot more than we鈥檙e used to.鈥
Cantua left for Mexico right after graduation to spend time with his family. He says he鈥檒l take a year off and start applying to graduate school with a goal of getting a Ph.D.
