I know someone (no, it's not me; I'm a US citizen) who came to the US as a 17-year-old with his father on a marriage-based petition and received a conditional green card. This was decades ago and he doesn't know whether or not conditions were ever removed. He wants to find out whether or not he is in status, but doesn't want to alert USCIS to his ongoing US presence if he is out of status. He is not aware of any removal proceedings' having been initiated against him. I've read the 2013 Privacy Impact Assessment (couldn't find the one from 2010 that is referenced all over the place), and I still can't tell whether he is at risk of alerting USCIS/DHS of his out-of-status presence if he is able to identify using the system, completes an authorization query, and the query comes up showing a mismatch because of expiration of his conditional green card. The data can be retained for up to 10 years, and it can be shared with Law Enforcement to discover and prevent fraud, but what exactly does that entail?
