...those who arrived in the United States before age 16, graduated from high school, and meet other qualifications could immediately enter the path to citizenship in exchange for at least two years' service in the armed forces.

Once they are made legal [amnesty] then they do become eligible. English proficiency and scores on entry tests must also be met. In 2000, about 530,000 Hispanic 16-to-19-year-olds were high school dropouts, yielding a dropout rate of 21.1 percent for all Hispanic 16-to-19-year-olds (U.S. Census Bureau, 2003). The Latino youth dropout rate was more than three times greater than the 2000 non-Hispanic "white alone" dropout rate of 6.9 percent. As a measure of the future schooling and social and economic prospects among teen populations, these aggregate status dropout rates clearly underline the disadvantages that Latino youth have, on average, upon entry to adulthood.

Yes there maybe other ways but this article is talking about those that meet the requirements for military service of two years and do so are allowed to enter the process to citizenship..... Dropouts don't fit the requirement of graduated from high school.
