deferral from deportation if they arrived before age 16, lived here for at least five years, be in school, have graduated or be a u.s. veteran and have no felony convictions. president obama calls the new rules fair and just, but republicans argue it is amnesty. the real world effect of these changes make a huge difference in the lives of thousands and cnn's nick valencia has one story. >> the change in u.s. immigration policy announced friday could impact the lives of hundreds of thousands of people. paula is one of them. >> i'm fighting for my case and that's why i'm here. >> reporter: standing outside the immigration court, the fight to stay in the united states began in april. the 18-year-old immigrant got into a minor car accident and was arrested for driving without a license. brought to the u.s. at 4 years old, she says the only home she knows is the u.s. going back to paraguay isn't an option. >> i don't remember anything. i don't know anything. yes, i have family, grand parents, but i've been here my whole life. i've given everything to this country that i have. >> good morning, everybody. this morning, we announced new actions by administration will take to mend our nation's immigration policy. >> reporter: but a change in policy announced on friday by the obama administration could give people like paula a renewed hope of not being deported. >> if i could do cartwheels, i would. >> reporter: her lawyer says it's not a certainty the new immigration would benefit her client. but she says she believes the latest announcement opens doors many others have been knocking on. >> this is unbelievable for so many young people. people under 30 years of age in the united states who are brought here by their parents, who have done the right thing and have gone to school and want to follow the american dream. >> reporter: she's scheduled to be deported in late august. if allowed to stay, she says she wants to join the navy and one day become a schoolteacher. while the change in u.s. immigration policy does make her eligible for work deferment and avoiding deportation, there are no guarantees. applications for stays of removal could take weeks, if not months. >> nick, thank you very much. earlier, i spoke with a young palestinian woman. her family came her when she was just 6. now she has a degree, and she's facing deportation in september. i asked her about what she thought of the president's announcement. >> this is a temporary fix. until congress can come up with a more permanent solution, until democrats and republicans can work together to come up with a permanent solution. but as long as congress is on a deadlock, this is what the president is doing to give at least undocumented youth who have been here a long time a chance to get work permits. so this gives us hope, if anything. >> her hearing is set for september. naturally, she's hoping to be able to stay where she grew up, and that is in chicago. always outspoken on immigration issues, the man nicknamed america's toughest sheriffs has been known to lock homes with the white house. but sheriff joe arpaio says he knows why the president made his announcement on immigration. >>

more and more young people doubt he does. or she, as well. a new survey asks the question, i never doubt the existence of god, agree or disagree? 68% of people 30 or under say they never doubt god's existence. what gives here? why the growing doubt? joining us now is jessie galiff, an atheist, and hemet mesa, the editor of the friendlyatheist.com. so what is an atheist? a person who denies the existence of a supreme being or beings. so jessie, i'm going to start with you. why do you -- first of all, i'm going toe ask you about that poll. why don't you believe? >> personally, i don't believe i was brought up in a secular household. i wasn't introduced to religion, i was taught morals without belief in a god or gods. it wasn't until i went off to college that i was exposed to other world views. i wanted to understand what people believed and became involved with the secular club. that's what more and more secular clubs are finding. >> hemet, why don't you believe? >> sure. i was raised in a religious family, but when i started questioning my faith for the first time in high school, i realized that not only did my faith not have the answers, but no faith had the answers. and like jessie said, when i went to college, i had the chance to explore that and wanted to become an activist in that area. >> you guys, both of you realize that you're the reason for what just happened, many people don't want to send -- or they're worried about sending their kids off to college because they'll become nonbelievers. i'm just being honest. jessie, how do you explain that survey from pew that shows there are less and less that believe or doubt the existence of god? >> i think that this is something we can all agree on in society that we should examine our beliefs and explore what we actually believe and why. and on campus, in colleges, even high schools and increasingly online, people are exposed to different world views and come in contact with challenging beliefs, challenging ideas. and people are brought up in an age with the internet. they're finding online communities, friendly atheists or other people who they can talk about and talk about their doubts. so the milenials in particular are able to doubt in a safe place. >> hemet, how is it that you can't believe in god? what is going on here? to be in this country, you have to believe in something and most people are christians in this country. what's wrong with you? it's the deterioration of this country. and people are being indoctrinated into secularism. >> we're asking people to think and question their faith and doubt their faith and pew survey said that's what they're starting to do more of. what they're finding is you can be good without god and you don't need a religious structure to make that happen. >> okay. it's important -- did you want to weigh in on this, jessie? >> yeah. i think something hemet said about the idea that you can be good without god. a real problem for these young americans who are starti ining experience doubt, there are all these stigmas, so erasing the idea that morality requires religion will go a long way. and our students are doing that. they're doing community service projects, helping rebuild houses in katrina, organize soup kitchen activities. because compassion is a human thing, not a religious thing. >> so it's important to note this, i think. you were just going to mention on line, hemet. this decline among young people under the age of 30, is it safe to say technology may be playing a role in this, for instance the onset of the internet allowing people to explore more? >> you can fact check what your pastor is saying in church. if you have doubts about your faith, there are communities online and increasingly on campuses and high schools and college where you can explore that without the fear of backlash. that's what we want to promote. we want people questioning and doubting. >> you guys, man, stirg up trouble. jessie, hemet, thank you very much. we appreciate it. >> thanks, don. >> thank you. tonight at 10:00, we're going to dig deeper. if more people continue to question the mere existence of god, decades from now, could that mean people just will stop believing? i'm going to play devil's advocate, so to speak, tonight at 10:00 eastern. the results of an election on the other side of the world could affect your bottom line and whether you get a loan for that new home or car. choosing the right schools for your child's early education can affect not only after-schooling but job choices. steve perry told us and picking the right charter school. >> i know that a charter school is founded privately. and i want to know what is the best way to research a charter school that best fits my family's needs? >> all charter schools are not private. some are run by the district, in fact. some are run by teacher's unions. but in te vent you're asking how do you pick the best one for you, i don't think that you can do the school justice by researching it online. you have to walk through the school and make sure it feels the way you want it to. go during the school day, not just when they have open houses. you've got to get to know the people in the academic community, watch how they go from one class to the other. the arts program is important to you. if they have sports or not. ask the questions important to you. so put together a list and visit the school. go visit the school. if you don't visit the school, you're not doing research. >> don't forget, stay connected. you can watch cnn live on your computer. you know what's exciting?
