Currently, migrant families are released in U.S. territory after crossing the Southern border without papers and surrendering to U.S. authorities to request asylum.
Starting October, however, the Department of Homeland Security (DHS) will no longer allow migrant families to move freely inside the country. This decision is expected to close the "legal gaps" which attract undocumented families.
According to DHS note, if immigrant families do not prove fear of persecution if returned to their countries, authorities will quickly send them back to their homelands. However, if they express fear of returning, families will be sent to Mexico following the Migrant Protection Protocols (PPM), which are known as the "Stay in Mexico" policy.
The tightening of U.S. immigration measures was confirmed by President Donald Trump in his speech at the United Nations General Assembly Tuesday.
“Today I have a message for open borders activists who claim to advocate for social justice: your policies are not fair... they undermine border security, they also undermine human rights and dignity."
