> In 2015 1,051,031 people obtained lawful permanent residence (https://www.dhs.gov/immigration-statistics/yearbook/2015/tab...). Illegal immigrants are estimated at 1,201,000 for 2015 (https://en.wikipedia.org/wiki/Illegal_immigration_to_the_Uni...). Is that really the definition of controlled? The "ratio" you stated is completely inaccurate.

You are comparing apples and oranges. Permanent residents (the green card holders as per definition in your link) contain ONLY a subset of legal immigrants.
