I think you're right in that the question of the title is really two questions. I tried to make that distinction clear in the analysis and conclusion sections.

I think you're right in that the question of the title is really two questions. I tried to make that distinction clear in the analysis and conclusion sections. I didn't actually try to find information on quota policies (specifically for Baltimore and Maryland) until I was writing the analysis section. I was expecting to be able to find a detailed description of policies by state (or something helpful) on Wikipedia, but that didn't really pan out [1]. I wasn't able to find any reliable information elsewhere either. I think the taboo attached to the subject may keep information about policies pretty far under-wraps.
