President Donald Trump is expected to sign another executive order. This one would stop the flow of refugees into the United States until stricter screening measures are available. There are more than 100 students at Virginia Tech who are from countries impacted by the executive order.

"Beginning today the United States of America gets back control of its borders," Trump said.

That means refugees from seven countries wouldn't be allowed into the U.S.

Yousef Jalali is from Iran and remembers how much work it was to get a visa to get to Virginia for his education. He's one of 142 students at Virginia Tech from the seven countries. Now he feels bad for anyone trying to do the same.

"The time that they invested for coming to the U.S. for, you know, continuing their education, they simply cannot achieve that dream," Jalali, a Ph.D. student, said.

Jalali says education was his top reason for coming to the U.S. But diversity in America is nearly just as important.

"I got to know many, many students from different nations, from different backgrounds, from different ethnicities. That was really rewarding for me," Jalali said.

But President Trump says these seven countries have terrorist ties and he doesn't want anymore attacks on U.S. soil.

"The world is a mess, the world is as angry as it gets. What you think this is going to cause a little more anger? The world is an angry place," Trump said.

However, Jalali says he doesn't like to label Iran or the other nations as terrorist countries.

"I would say you need to bring a better justification to the table. Unless I see that justification, I'm definitely against that kind of proposal," Jalali
