Suddenly entire lives were held in lembo. 109 people were on their way to america and denied entry, according to the white house. Instant chaos and confusion erupted at airports. A number of travelers to the u. S. , including children, detained upon landing. Tears of joy when this mother in virginia reunited with her 5yearold son. I dont know what to do. Because i sold my house. I quit my job. My wife quit her job. And kids left school. Reporter abdullah was vetted. Hes been in this country six years, working on a perfectly legal religious workers visa. He says he loves this country and doesnt think the policy will abate terror. This type of decision, it will only promote hate and fear. And it will not solve the problem of extremism. Just the other day, that canadian white man, he entered the mosque in quebec and killed eight people while they were praying. So we will not we dont say we have white men are terrorists, thats just foolish, that is very unjust and very unfair. So this decision is very discriminatory, very discriminatory, very unjust, very inhuman. Reporter he got up sunday morning and joined others determined to have their voices heard.

Its just like jumping when the plane goes into a crash mode, first you have to put on your mask to help your child. I think we need first and foremost is to keep our country safe.

But i think the president would much rather know that hes not placing a call to someone who was killed because someone was let into this country to commit a terrorist act. Reporter the order grants some exceptions, giving priority to refugees from religious minorities like christians living in majority muslim countries. Ramin, clinical law professor and attorney, says she believes the mandate is unethical and unlawful. Weve seen post9 11 in the name of security our country has allowed itself to erode many of its values. If the u. S. Is now going to prioritize, take refugees that are christian over refugees that are muslim, that in and itself is discriminating based on religion. Reporter the president claimed the ban had nothing to do with religion. Its not a muslim ban, were totally prepared to work it out very nicely.

Ultimately we fear this executive order will be become a selfinflicted wound in the fight against terrorism. President trump firing back on twitter, john mccain and Lindsey Graham should focus their energies on isis, illegal immigration, and border security, instead of always looking to start world war iii. After it was signed there was a lot of confusion at airports around the country. We had Young Children who were detained. We had the elderly. It was a very serious situation.

President trump has long vowed to institute a process of what he calls extreme vetting for refugees from predominantly muslim countries. As world news tonight anchor david muir found out that vetting process can already be very rigorous. They followed families from their home in jordan to communities across america to learn about their experience firsthand. Let them go reporter there is anger and confusion around the country in the wake of President Trumps controversial travel ban. Donald trump has got to go reporter with the stroke of a pen on friday, the president s executive order suspended the decadesold Refugee Resettlement program for 120 days. And indefinitely banned all Syrian Refugees. This is a muslim ban . No, its not a muslim ban. Its countries that have tremendous terror. Reporter the president promising this. Were going to have extreme vetting in all cases. I mean extreme. And were not letting people in if we think theres even a little cans of some problem. Reporter the president s critics argue the vetting already in place was more than sufficient. What do we want . Justice reporter in 2016, more than 12,000 Syrian Refugees were admitted to the u. S. Before the election we krafled to amman, jordan, to see what the vetting entailed. In jordan across the Syrian Border there are over 600,000 Syrian Refugees. Despite the backlash in the u. S. , so many of them are desperate for the chance to go to america. Through this doorway, we immediately discover a crush of humanity. Refugee families already screened by the u. N. Now waiting to be interviewed by the u. S. How many interviews . Four interviews. Actually, five. Five interviews. So they come through here . Yes. Reporter gina is with the u. S. State department. Theyre brought into a security screening area. Reporter for a vetting process that can last two years. We are taken to a hallway lined with small rooms and through the windows, we can see family after family being interviewed. How can you possibly learn everything about a family through an interview . Id say the interviewers are very highly trained. They are trained to look at the documentation, but also for the credibility behind the applicants story. When you say documentation, this is syria. Theyve been at war for years now. What kind of documentation do they have, teif any . 90 of adult applicants in our pipeline have valid syrian documentation. Reporter from here they are screened through the terrorist watch list, the Intelligence Data bases back in the u. S. , and Homeland Security makes the final decision. Are there times when it will flag you a particular family, and they get pulled . Absolutely. The applicants at airport, we had to prevent them from boarding the plane. Reporter the u. S. State department told us of the over 800,000 refugees admitted to the u. S. Since 9 11, a tiny fraction of 1 have been arrested or removed because of terrorism or concerns. Critics say thats still too many. They point to the case of iraqi refugees in bowling green, kentucky, who the fbi caught in 2011 attempting to buy an antiaircraft missile they thought would be used against American Forces in iraq. They were known insurgents who had fought against u. S. Soldiers. But still slipped through the cracks. After that incident, president obama drastically curtailing the number of iraqi refugees coming into this country for six months. The vetting procedures overhauled. Those enhanced measures were firmly in place last year when we met these families who had just been cleared for america. This is cultural orientation. Where theyre caught about their new home. The teacher asks them, whats allowed in the u. S. , whats forbidden . She shows a picture of a couple kissing in public. She asks them about drinking in america. Then she asks about polygamy. Asking if its legal in america. They begin to clap. The next lesson about america, the melting pot. Theyre asked a simple question. Which of these faces are american . These families leaving within days. How many of you are excited to go to the United States . Give me one word that describes america to you. The land of chances. For americans who are worried about refugees coming to the u. S. . Theyre humans like you. We want to be one of you. Reporter we wondered if they had any questions for us. Well take that question back to the United States. Reporter all the families in this room have already been admitted to the United States. But there are thousands of others now stuck in limbo. Just last week, i asked President Trump about the critics who say his ban will only inflame tensions both here in this country and overseas. Are you at all concerned its going to cause more anger among muslims around the world . Anger . Theres plenty of anger right now, how can you have more . You dont think it will exacerbate the problem this. Look, david. I know youre a sophisticated guy. The world is a mess. The world is as angry as it gets. Reporter it was during our trip we found another family in amman who had been waiting nearly two years for an answer. Their home bombed in syria. They show me their homemade swing in the hallway. The children miss their playground back home. This is your playground . Yes. Reporter the u. S. State department then tells them theyre next. On september 6th, you will travel to kansas city, missouri. Reporter we watch as it sets in. Then a question from their father mustafa. We show them on a map. Kansas city is a beautiful city. Its a beautiful city. And the baseball team, they won the world series. Reporter a smile from the son who loves sports. But we notice tears from one of the children. Her mother tells us she is sad to leave her friends yet again. Since our trip, we have followed their story. They arrived here in the u. S. In september to a warm welcome from their new community. And since then, mustafa has landed a fulltime job at a local auto parts factory. The kids are thriving in school. But he knows he may not be able to share this promise of a better life with relatives who have yet to arrive. An uncertainty now shared by thousands of refugees who had pinned their hopes on a new beginning in the United States. For nightline, im david muir in new york. Our thanks to david.
