I'm in the complete minority category of "mixed" feelings.  I do understand the benefits of the proposal, but it's not a black and white issue.  There are some immigrants who come, speaking poor or no English but end up opening successful businesses and eventually learning the language well enough to converse.  Then there are some who may be educated and fluent in English but end up committing crimes.  Already, there have been cases where newly minted American citizens commit acts of terror, then compare that with the Mexican coffee farmer in Kona who came here as a teen and ended up building a successful farm and business.  And what about our own homegrown born and raised American citizens who commit crimes?
