Migrants children, who are part of the Central American caravan, vie for candy tossed out to them by a social worker at a shelter in Tijuana, Tuesday, Nov. 20, 2018. U.S. border inspectors are processing only about 100 asylum claims a day at Tijuana's main crossing to San Diego, and there was already a waiting list of 3,000 when the new migrants arrived, so most will have to wait months to even be considered for asylum.
