This page highlight practice guides on U.S. immigration law and procedure, as well as sources for federal cases and administrative decisions.
Many of these practice guides cover Special Immigrant Juvenile Status at least briefly. See the notes for each guide for the SIJS sections of that guide. Or, run a search such as the following:
"special immigrant" /10 juvenile [for Lexis]
"special immigrant" /s juvenile [for Westlaw]
Most of the guides also touch on refugee/asylum law and procedures. See the notes for each guide for details.
