Tough to say. She could introduce a bill (and the more cosponsors she has the better chance it has) to provide financial assistance to immigrant women, and introduce other bills to limit access to guns.
If it helps, the way bills get passed is they are written and sponsored by a representative or senator, and once it's introduced it will go to a committee, where it is picked over and if it comes out of committee (most bills die in committee and never get voted on) it will go to the House floor for debate and vote. If it passes, it goes to the Senate, where it will go to a committee, where it will be picked over and probably changed. If it makes it out of the Senate committee, it will be debated and voted on on the Senate floor. If it passes, it will go to another committee that will resolve any differences between the House and Senate versions. Then it goes to the President, who either signs it or vetoes it. That's the quick version, and an internet search will tell you all you need to know about the process.
