[quote=deadzone]Well they do know that if they manage to elude border patrol, there is very little chance they will ever be deported and they will be able to live and work in relative peace.
They also know that if they have a child born here, that baby will be instant US citizen and through their baby they will start qualifying for welfare.
Additionally, they do know there was a mass amnesty in the 1980s, and politically there is push for it again (AKA “immigration reform”) so they have reasonable hope and expectation that if they stay here long enough, they will eventually be granted citizenship.[/quote]
I think the way it works is they come across, they get caught,they get processed,they get released here in the US,they don’t show up for court and then stay here as long as they are never arrested again.
