DEAL: Bipartisan deal on immigration

Key points revealed so far:

Illegal immigrants can come forward and obtain a "Z visa" and—after paying fees and a $5,000 fine—ultimately get on track for permanent residency, which could take between eight and 13 years. Heads of household would have to return to their home countries first.

They could come forward right away to claim a probationary card that would let them live and work legally in the U.S., but could not begin the path to permanent residency or citizenship until border security improvements and the high-tech worker identification program were completed.

A new temporary guest worker program would also have to wait until those so-called "triggers" had been activated.

Those workers would have to return home after work stints of two years, with little opportunity to gain permanent legal status or ever become U.S. citizens. They could renew their guest worker visas twice, but would be required to leave for a year in between each time.

New limits would apply to U.S. citizens seeking to bring foreign-born parents into the country.
