Mexico has struggled with how to respond to increased migration from Central America since the 1980s. In the early 1990s, Mexico made it easier for some migrants to enter but stricter for others and cracked down on illegal immigration. More recently, violent attacks on migrants pushed immigration reform up Mexico's agenda. In 2011, Mexico passed a new immigration law that aims to respect migrant rights, facilitate legal migration, meet labor needs, and promote integration, though critics note it does not address corruption issues.
