"Should illegal immigrants be required to go home before becoming eligible for U.S. citizenship?"
The law as it stands is that YES, you can only be 'reclassified' if you entered here legally.
Some may be allowed to go to Canada, etc., but they have to leave first in order to make a 'legal' entry.
Of course, laws are 'flexible' so who knows where this will end up???
The issue facing Congress this week isn't about legal immigration.
