Mona Zabihian, an Iranian American, attempted to return to Washington state from Canada late Saturday after attending a concert — a trip she said she makes several times a year with no issues. This time was different, Zabihian said, as she and dozens of others were questioned and held for hours.

“We went inside, we saw a bunch of other Iranians, pregnant woman, children. I saw one of my friends from Seattle,” she told NBC News.

Immigration authorities asked her about her social media accounts and the last time she had been to Iran.

“They asked if I was in the military or had anything to do with guns,” she said, adding, “We were there from 11 p.m. to 4 a.m. on Sunday.”

Zabihian claimed that one agent said, “You guys are all U.S. citizens, you should not have to go through this.”

“He mentioned that this was not a nationwide order. It was only a Washington border order,” she said.

Kiara Vaziri, an Iranian American, said she and her family were also traveling back to Washington from Canada on Saturday when they were held for questioning “without explanation.”

She said authorities took her passport and car keys and she and her family were questioned and made to wait for four hours.

“Some people got their phones taken away and were told to give their iPhone, Facebook, and Instagram passwords,” she said.

She and her brother, who have never been to Iran, were asked only three questions, Vaziri said, but her parents were asked a series of questions about their backgrounds, including, about “high school, their parents, their siblings, if they ever served in the military, when they last traveled to Iran, if they had any clan/militia affiliation, and more.”

"We walked in thinking it was just a ‘random’ search as a formality, being that it hadn’t been the first time we were chosen for ‘random’ secondary screening at airports and what not,” she said. “Once we got inside, we realized that it was not only full of minorities, but Iranians."

John Ghazvinian, an Iranian American and a U.S. citizen, said he was called into a secondary room and asked about his thoughts about the situation in the Middle East.

“I said something like I don’t see how that question is exactly relevant to what’s going on,” he said.
