Most likely.
But it is a fool's choice. Amnesty generally applies to those convicted of a crime. For the millions of illegals that have not been convicted, it wouldn't be an option.
Now if the gov says it applies, then my choice is both. Amnesty as a matter of record with serious jail time if they come back and send them home.
Being here illegally is a crime, a misdemeanor. If you have been deported previously and return, it is a felony punishable by up to five years in prison. It is illegal to work here for an illegal or for an employer to hire him. Illegal aliens commit other crimes like identity theft, creating false SSNs, etc.
