WASHINGTON – Democratic and Republican negotiators have reached agreement on all the major elements of sweeping legislation to remake the nation’s immigration laws and expect to unveil the bill next week, lawmakers said Thursday.

After months of arduous closed-door negotiations, the “Gang of Eight” senators, equally divided between the two parties, had no issues left to resolve in person, and no more negotiating sessions were planned. Remaining details were left to aides, who were at work completing drafts of the bill.

“All issues that rise to the member level have been dealt with,” Sen. Chuck Schumer, D-N.Y., said in a statement. “All that is left is the drafting.”

Democratic Sen. Dick Durbin of Illinois said the bill probably would be introduced on Tuesday. The landmark legislation would overhaul legal immigration programs, require all employers to verify the legal status of their workers, greatly boost border security and put the estimated 11 million immigrants living in the U.S. illegally on a path to citizenship. A top second-term priority for President Obama, it would enact the biggest changes to U.S. immigration law in more than a quarter century.

Deals gelled over the past day on a new farm-worker program and visas for high-tech workers, eliminating the final substantive disputes on the legislation.

Next will come the uncertain public phase as voters and other lawmakers get a look at the measure. Already, some on the right have made it clear their opposition will be fierce.

Sen. Jeff Sessions, R-Ala., complained that the bill will ensure that millions get amnesty but border enforcement never happens. “This is also why it is so troubling that (Senate Judiciary Chairman Patrick Leahy, D-Vt.) has rejected the GOP request for multiple hearings and that members of the Gang of Eight have publicly announced their intention to oppose any amendments,” Sessions said in a statement Thursday.

Once the legislation is released, it will be considered by the Senate Judiciary Committee, which has scheduled a hearing for Wednesday and will likely begin to amend and vote on the bill the week of May 6. From there, the bill would move to the Senate floor.
