Agreed. I have a few more issues, too:
How well do they know Cali State law?
How good is their English?
Will they be culturally sensitive to minorities (including gay people)?
Are they willing to integrate into American society?
Which country did they come from? Is it a country hostile to the US?
Where are their documentation papers?
You questions, although valid, speak to the common misconception that all undocumented immigrants are poor cherry picking, non english speaking ignorant people. The truth is that you would be surprised by the number of college educated undocumented immigrants that there are. A lot of them are more American then people who were lucky enough to have been born here and know and care more about America then a lot of their citizens. In fact, many would welcome the chance to be able to fight for America and join the armed forces.
