U.S. Immigration and Customs Enforcement (ICE) determines citizenship status through a variety of methods and sources. Here's how they typically proceed:
ICE requires individuals to provide proof of citizenship. Acceptable documents include passports, voter ID cards, birth certificates, or naturalization certificates. If someone claims to be a U.S. citizen but cannot immediately prove it with such documentation, they might be detained until their status can be verified.
During encounters, ICE officers might interview individuals to gather information about their citizenship or immigration status. This can involve questions about place of birth, family background, and immigration history. If there's a claim of U.S. citizenship, the burden of proof generally falls on the individual to demonstrate they are not an alien, although legally, ICE must establish probable cause that someone is not a U.S. citizen before pursuing further action.
ICE has access to various databases, including those from state departments of motor vehicles (DMVs) through networks like Nlets, and criminal justice databases like the National Crime Information Center (NCIC). These databases help in cross-referencing the information provided by individuals against records that might indicate citizenship or immigration status. However, these databases are not always 100% accurate, which can lead to errors in determining citizenship.
When someone is arrested by local or state law enforcement, ICE might place an immigration detainer if there's a suspicion of illegal presence. This involves further investigation into the individual's citizenship or immigration status, often leading to interviews in custody. If there's evidence suggesting U.S. citizenship, it should be investigated further, but instances of U.S. citizens being detained due to database errors or miscommunications have been documented.

Brad could've answered his own question quickly and easily, IN MERE SECONDS, the same way I did.
But he still hasn't
Guess why.
