An immigration reform bill passed an important test in the U.S. Senate on Monday.
On Monday, 67 senators voted to keep a border security amendment in the bill.
Supporters are hoping that amendment will help the legislation gain bipartisan support, especially in the Republican-controlled House of Representatives.
The bill would give millions of immigrants living here illegally a path to citizenship.
It has strong support from President Barack Obama.
The U.S. Senate is expected to vote on the full bill later this week.
