When Fordham University moved to online classes, Shaojie Zhang decided to stay in his apartment on New York’s Upper West Side.

His decision upset his parents, especially his mother. “My mom got super worried,” said Zhang, who goes by Carter. “She wanted to buy me a ticket to come home.”

His situation isn’t an uncommon one. As the coronavirus spreads across the United States, many international students are faced with a decision, to stay or go?

With the federal government relaxing visa regulations to permit international students to take courses online whether they remain in the U.S. or travel overseas, some students are opting to return to their home countries. While most American colleges are permitting international students and others with no place to go to stay on campus during the outbreak, they may prefer to be with family and friends. Others are from countries or regions with relatively low infection rates. Anticipating global travel bans, some fear if they don’t leave now they may be stuck:

And the slow American response to the public-health crisis has led many to conclude they would be safer back home, even when home is China, the original epicenter of the outbreak.

Zhang’s parents in Beijing were confined to their home for weeks, only able to leave their neighborhood with a special pass. “I was so worried about them,” he said. “Now they are worried about me.”

In a WeChat group, anxious Chinese parents shared data about coronavirus cases in their children’s college towns, swapped details about online marketers who would ship face masks to America, and fretted about empty store shelves. “No eggs, no protein,” one mother wrote about her child’s aborted trip to an American grocery store, appending a sobbing emoji.

Andrew Chen of WholeRen Education, an international-education consulting company, has been organizing hourslong virtual Q&A sessions for parents with Chinese-speaking officials at American colleges and high schools. They have fielded hundreds of questions. “There are a lot of concerned parents,” he told me.

Still, Chen is unsure whether there will be mass departures of students to China. In a WeChat survey of 600 parents he conducted last week, just 2 percent said their children were now in China.

One reason students may hesitate is China, like many countries, has put in place quarantine rules for travelers from abroad, confining them to special quarantine hotels for 14 days. Returning students have also been subject to social-media criticism from people who worry that they will increase infection rates just when China seems to have gotten the epidemic under control. SupChina, a news site focused on China, details some of the vitriolic comments posted on students’ accounts: “Why did you come back? So your foreign dad is not as good as you thought?” and “The quarantine seems like a vacation for you. Luxury hotel, single room, wifi, food…you are in luck!”

Zhang, who is studying for a master’s degree in quantitative finance, said he feared that a long trip with hundreds of strangers who had not been tested for COVID-19, the disease caused by the coronavirus, put him at far greater risk than self-isolating in his studio apartment. His parents came to agree.

Zhang was also concerned about how he would navigate a 12-hour time difference if most of his classes continued in their regular slots. International students can face other logistical hurdles — platforms used for online learning like Zoom or Google Meet, for example, are not licensed and available in all countries.

Still, several of Zhang’s friends decided to return home, scrambling to find flights out of New York. As America hunkers down, it’s far from clear when they, and other international students, will be back.

NAFSA: Association of International Educators is asking federal officials to publish a notice of Special Student Relief, or SSR, in the Federal Register that would allow the government to temporarily suspend or alter student-visa rules for certain groups of international students because of unusual circumstances. In a letter, Esther Brimmer, NAFSA’s executive director, asked the government to invoke SSR to give colleges flexibility on issues including duration of status and employment eligibility as they respond to the coronavirus outbreak.

SSR has been used twice before, for Nepali students following a 2015 earthquake and for students from Libya and Syria affected by civil unrest in their home countries.

The government has promised colleges greater latitude on international-student regulations and has published guidance on how to navigate the rules. Yet a great deal of uncertainty remains. I asked on Twitter what some of the big unknowns are for international educators in advising students. Here’s some of what you told me:

Of course, the anxiety isn’t limited to visa regulations. From the cancellation of standardized tests like the SAT to closures of embassies and consulates around the world to the biggest question of all, will families still send their children abroad to study, little is assured in international education today.

A cancer researcher at the University of Florida left the United States in 2019 amid an inquiry into his alleged failure to fully disclose his Chinese academic appointments and funding. Now, Weihong Tan leads a team of 300 Chinese scientists who worked to develop a fast, easy test for COVID-19. HIs case illustrates the potential costs of the U.S. government’s stepped-up investigations of researchers for not disclosing foreign ties.

Hey, that’s me on the Education Writers Association podcast, talking about covering the coronavirus.

In the Bay Area, we’ve wrapping up week one of a mandatory shelter in place. Cooped up inside, it can be easy to let the work day seep into free time. (Just me? OK.) I’m trying to remind myself to let the stress out. Here are a few things that have been making me smile:
