Prohibits the housing of migrants in schoolhouses or on such grounds

This bill prohibits New York City public school buildings and grounds from being used to house migrants, either permanently or temporarily. It requires school districts to establish a formal policy banning such use under New York State education law. The law directly affects NYC public schools and their operations, preventing the repurposing of school facilities for migrant housing. The policy takes effect immediately but is set to expire when the relevant education law section reverts, per the bill's language.
