immigration

Hi-
I'm doing an article about a recent case in which 80-100 workers at Best Brands were laid off because their social security numbers were incorrect after the company did an internal audit. I was wondering if there is a legally mandated amount of time an employer is supposed to give an employee if there is an error found with his SSN#. I know that for employees that receive a no-match letter it's 90 days, but this is different because it comes from an internal audit that the company voluntarily did. In this case, when the Social Security Administration hasn't been involved, is the employer still required to give employees a certain amount of time to fix discrepancies?

The focus of our project is identifying the effects of globalization at the community level. We are trying to identify data and information resources that demonstrates trends in the internationalization (i.e. migration - including migrant sending and receiving countries/communities - and international trade patterns) and then tying those to a generation (last 15-20 years) of primarily neoliberal foreign and economic policy choices. The goal is identify 12 communities for further study on local impacts and the ways communities respond to the positive and negative aspects of these trends.

I am looking for any sources (preferably written, and preferably scholarly) on undocumented youth and activism. More broadly, stuff on undocumented youth in general from the last 10 years or so would be helpful. I am looking for books, journal articles, dissertations, etc - anything with "scholarly merit".

thanks, radical reference people!
