WASHINGTON (AP) — A new Biden administration policy will give roughly half a million immigrants who are married to American citizens but lack legal status in the United States a pathway to citizenship for them and their children. It is one of President Joe Biden’s most sweeping immigration policy moves and one that migrant advocates had been heavily lobbying the administration to undertake. It will avoid what can be lengthy separations of families with the migrant spouses leaving the country to apply for legal status. It comes as other Biden immigration policies have made it much more difficult to qualify for asylum at the southern border and intensified removals of those who don’t qualify to stay.
