MIAMI - Marlon Morraz, 19, an undocumented immigrant from Nicaragua, wasted no time to sign up for temporary legal status in the United States under the Obama administration's relaxed deportation rules that took effect on Wednesday.
"Now is my chance," he said after picking up an application form at an immigration workshop hosted by a Miami congressman. "I'm pretty elated. Now I have a future."
Morraz, who has been living under the radar since he came to the country when he was 11, is among hundreds of thousands of undocumented immigrants expected to file applications with the Department of Homeland Security under the new rules.
The "deferred action for childhood arrivals" permits shield them from deportation for at least two years as long as they were younger than 16 when they came to the United States, have lived in the country since June 15, 2007, have not been convicted of a felony, and are not older than 30.
Lines of eager, young undocumented students formed outside immigration offices in states with big immigrant populations such as California and Texas on Wednesday.
As many as 1.7 million people could qualify for the temporary program, which enables them to apply for work permits, Social Security cards and driver's licenses, according to the Pew Hispanic Center.
President Barack Obama, whose administration has aggressively deported illegal immigrants with criminal backgrounds, announced in June that he was moving to help this group of youths - many of them Hispanic - who have become increasingly vocal in calling for help.
Many Republicans blasted the move as the Democratic president's grab for Hispanic votes ahead of the Nov. 6 presidential election, with an eye on battleground states such as Florida, Nevada and Colorado with big immigrant populations.
Morraz, who graduated from high school last year with advanced credits, had to turn down university opportunities at Boston College and the University of Chicago, because his lack of status made him ineligible for financial assistance.
"I started to stop caring about education. I thought it was a waste of time, it just fills your head with dreams for nothing," he said.
Now he has enrolled at a community college to study international relations, and has revived his university dreams with hopes one day of becoming a diplomat.
"Now I have a future. I'm on a path," he said.
The federal policy change has been warmly received by Latino leaders, but has been derided by some Republicans as "backdoor amnesty."
Immigration advocates are not entirely satisfied either, calling the policy just a partial implementation of the Dream Act, a bill stalled in the U.S. Congress that seeks to create a permanent legal status for the undocumented children of immigrants who entered the country illegally.
"It's like a Band-Aid," said Daniela Pelaez, 18, a Colombian-born student who came to Miami at age 4. "It's only temporary and we don't know what happens in two years time."
Pelaez and her sister received a 30-day deportation order in February and led a public battle to stay in the country after Daniela was elected to deliver her high school's valedictorian commencement speech.
Pelaez was awarded a full scholarship to Dartmouth to study molecular biology and won a separate appeal for deferred action in March, spurring calls for the Obama administration to apply the remedy more broadly. She starts at Dartmouth in two weeks and hopes to become a heart surgeon.
"All these children have the ability to be great Americans. The only question is whether we give them that opportunity," said U.S. Representative David Rivera, a Florida Republican who hosted Wednesday's workshop to advise applicants for the program.
"I'm not so concerned about the mechanics of how this was done," he added, referring to criticism of president Obama's executive order, "as much as I am about it's being a foundation for a permanent solution."
Advocates are urging young immigrants to have their applications reviewed by an attorney before filing them.
"Mistakes or misunderstandings could lead to denial of deferred action and losing the $465 fee or worse - deportation," said Cheryl Little, director of Americans for Immigrant Justice. "This is a marathon, not a sprint."
San Antonio, Texas, resident Benita Veliz, 27, hoped to take advantage of the program. She arrived in the United States from her native Mexico with her illegal immigrant parents when she was 8. Since then, she said she has completed high school and college but has been unable to get a driver's license or travel.
"This will allow me to do the things I've always wanted to do and live out the American dream like I've always wanted," she said.
