International students in the Bay Area are discovering their student visas have been revoked.
Stanford University recently announced that six visas had been canceled for four current students and two recent grads. The university said it only found out by checking its database and that no official reason had been given.
NBC Bay Area confirmed on Saturday that at least four student visas were canceled at the University of California, Berkeley. According to university officials, the student visas were canceled across several campuses.

In a statement from the president's office, the UC said it's committed to supporting its students’ rights and it is monitoring the situation.
While no reasons have been given for these visas being revoked, across the U.S., many students in a similar situation have engaged in political activism.
"Within immigration law there's reasons, legal reasons that the government can allege to try to revoke a student visa," said Ariadna Renteria, an immigration attorney.
Recently, Secretary of State Marco Rubio said at least 300 visas had been canceled this year and that he'd take any legal means to remove students he accused of being harmful to the U.S. or its foreign policy.
While the universities said they're in the dark about why student visas were canceled this week, the Trump Administration has warned of taking such actions. The administration has cracked down on activists like Columbia University's Mahmoud Khalil, who was arrested last month for his role in leading pro-Palestinian campus protests, which federal officials called activities that quote "Aligned with Hamas."
At UC Berkeley, where Pro-Palestinian student activism has at times turned violent, students said they are worried.
"A lot of activism, a lof ot international students speaking their voice," said Mika Zaman a senior at Cal. "I've even encountered a student who spoke about his personal family in Palestine, so I worry about students like that."
Other students expressed anger and said what had happened was "unfair and discriminatory."
"One of the craziest things I've seen in my entire life," said Yashal Sarfaraz. "These are such hard-working students. They don't deserve this kind of uncertainty."
Stanford and Cal administrators told NBC Bay Area that they are providing resources to the students who had their visas revoked and retain legal assistance.
