(9) Do immigrants have the right to post bond? Yes, but most of them don't have the wherewithal to do this. A June 24th New York Times article (click here ) described the case of a Guatemalan woman who was separated from her son but who was aided by the organization Libre by Nexus; they gave her legal advice, put up her bond, and instituted a lawsuit that resulted in reconciliation.
(10) Can their children be held indefinitely? No. There's a 1997 court decision (Flores v. Reno) that requires the federal government to to place children with a close relative or family friend "without unnecessary delay," rather than keeping them in custody. (In practice, it limits the custody to 20 days.)
On June 23rd, the Trump Administration announced a process to reunite the 2053 "separated minors," it has in custody, with their parents. As part of this process, the Department of Justice will seek to revoke the Flores decision so that it can hold minors, and their parents, indefinitely.
Summary: Not surprisingly, Trump has exaggerated and lied about the immigration situation. It's not a crisis. The vast majority of the immigrants are not criminals, they are unfortunates legitimately seeking asylum. The solution to the situation is to grant immigrants due process and, for legitimate asylum seekers, releasing families from custody until they can have their day in court.
