The specific lawsuit before the court involved TPS protections for over 300,000 individuals from Haiti and several thousand from Syria.
These individuals are now expected to lose both their protected status and their legal work authorizations once the ruling takes effect.
Kagan stated that the government could immediately deport these individuals if they lack alternative legal pathways like asylum.
Homeland Security Secretary Markwayne Mullin stated that current TPS holders should look for permanent residence pathways or prepare to leave the country.
This directive comes despite the fact that TPS provides no direct pathway to obtaining a green card.
The ruling directly impacts individuals like Fritz Emmanuel Lesly Miot, a California-based Haitian Alzheimer's researcher with type 1 diabetes.
Miot faces severe health risks if returned due to limited medical infrastructure in his home country.
Similarly, Laila Doe, a Syrian behavioral technician living in Illinois, expressed severe safety fears regarding a forced return to Syria.
The ruling sets a legal precedent that hampers judicial review for all nationalities holding TPS, simplifying termination efforts by the administration.
Five other nationalities currently maintain their TPS protections solely because of existing court orders that this ruling may influence.
The US State Department currently maintains its highest "do not travel" advisory for both Syria and Haiti due to severe safety risks.
Official warnings for Syria highlight ongoing threats of terrorism, civil unrest, kidnapping, hostage-taking, crime, and active armed conflict.
In Haiti, the department warns of rampant violent crime, expanding gang activity, armed robberies, sexual assaults, carjackings, and random gunfire.
