“Migrants typically get information about the conditions on the border from people in their network who have successfully made the journey, rather than from top-down declarations from US officials. Smugglers have also sought to spread misinformation about the Biden administration’s plans to process asylum seekers. Immigrant advocates on the border have reported hearing rumors spreading that migrants staying in certain camps will be processed or that the border would open at midnight.
These rumors have survived on the hopes of people who have long aspired to migrate. Many of the people arriving on the southern border are fleeing dangerous or unlivable conditions and felt they had no choice but to leave their home countries.”
