What does Abba tell the border officer in Section 2: Chapter 2? What does the officer respond?

Reaching an officer, Abba explains his family is applying for asylum, but the officer says they are overwhelmed with immigrants and the Hossains must return to America. He warns them one of them will probably be arrested if their visas are not current, but if they can put together about $5,000 for the bond, they can try to apply for asylum in Canada again in a few weeks.
