Ten American Baptist missionaries from Idaho are still waiting for a Haitian judge to decide whether they will be charged with child trafficking.
Idaho congressional leaders said they are closely monitoring the situation to make sure the missionaries have adequate food, water and medical treatment.
Haitian authorities stopped the missions team at the border between Haiti and the Dominican Republic as they tried to bring 33 alleged orphans across.
The missionaries had no passports for the children, only a note from a Baptist pastor in Haiti.
"What we were told was that the pastor could basically write a statement with all the names of the children verifying their identity and the fact that their parents were deceased and signed the statement," said Laura Silsby, spokeswoman for the group and member of Central Valley Baptist Church.
The group's Web site states they planned to gather 100 orphans from the streets and collapsed orphanages and bring them to a temporary shelter in the Dominican Republic.
