Nope. Illegal entry if done in the search for Asylum is plenty legal. Its also donee because:
In January 2017, the American Immigration Council (AIC) filed a complaint about the DHS’s practice of turning away asylum seekers at ports of entry. Human Rights First documented numerous other cases in May 2017, concluding that the policy “is pushing some asylum seekers to dangerously cross the border between formal entry points.” In July, AIC filed a class action lawsuit challenging the policy. In December 2017, NPR reported that DHS officials at a port in San Diego were telling asylees from Central America “they can’t come in.” In June 2018, the Atlantic published video of asylum seekers being turned back at ports of entry—one man was turned back 20 times in four days. This forced them to sleep homeless under a bridge in Mexico. The same month, the Intercept reported on the officials in Texas rejecting asylum seekers from Central America, producing video of the illegal actions, and the Washington Post reported on a father with a 15-year-old son whom CBP officials had rejected nine times over the course of nine days.
In April 2018, Secretary Nielsen herself admitted this was happening and said, “We are metering, which means that if we don’t have the resources to let them in on a particular day, they are going to have to come back.” It is illegal under 8 U.S.C. 1158 to refuse to allow a person to submit an asylum application. It takes minimal resources to process an asylum claim, so the idea that they need to stop processing now is baseless. Moreover, because the practice has forced homeless, hungry, and desperate people to cross between the ports, DHS still has to process the claims, while at the same time, it has chosen to expend resources to arrest them, refer them for criminal prosecution, and house the children in detention facilities—all of which is more expensive than processing the original claim.
