The thing to do is get the borders closed first. Once you really secure the borders, you can grant amesty to those staying here. Make them register, and kick out all the criminals among them. Then after say a six month grace period, any illegals found in the country go to prison for 10 years, and then get deported. That would give them incentive to register.
