After immigration reform failed to be resolved in 2013, supporters hope for a narrow window of opportunity in late spring to push legislation through the House. The timing allows the primaries to pass and reform “certainly gets easier,” said Jeremy Robbins, the executive director of the Partnership for a New American Economy.

Filing deadlines for primary candidates could play a role in the timing of any immigration legislation.

“It depends where you are. I know in my delegation, they’re not concerned about primary challengers over immigration,” Kentucky Rep. John Yarmuth said. “On the other hand, I think Texas matters.”

Earlier this month, House Majority Leader Eric Cantor (R-Va.) sent a memo to members, listing immigration as one of the issues to be brought to the floor during the next few months, according to Politico.
