Obtaining Asylum in the United States
The two ways of obtaining asylum in the United States are through the affirmative process and defensive process.
Affirmative Asylum Processing With USCIS
To obtain asylum through the affirmative asylum process
you must be physically present in the United States. You may apply for asylum status regardless of how you arrived in the United States or your current immigration status.
Of course, dumb fucks like you think that Trump preventing them from entering so they can apply for asylum is completely "legal".
