Jose Antonio Vargas is an illegal immigrant whether he likes the term or not. His parents sent him to the US at age 12 to live with his grandparents without obtaining the correct clearance from the government. People who drive without a license are called illegal drivers; people who thwart immigration law are called illegal immigrants.
Supporters of the DREAM Act tell us that illegals who come here as young children don't know their country of origin. Vargas lived in the Philippines until age 12 which (under the DREAM Act standards) makes him far more attached to the country where he was born than the United States. He also works is a white-collar industry and is taking work from qualified American citizens.
