What does RTI refer to in the context of immigration proceedings?

In the context of immigration proceedings, RTI stands for "Referral to ICE." This term is used when an immigration officer refers a case or individual to the Immigration and Customs Enforcement (ICE) for further action or investigation. In various scenarios, such as when an individual is suspected of violating immigration laws or when there are concerns related to criminal activity, the officer may determine that the situation requires the involvement of ICE.

The other options do not represent established terminology within the immigration context. "Returned Temporary Immigration" suggests a concept not commonly recognized in immigration proceedings. "Regulatory Tracking Index" implies a framework for documenting regulations but does not align with immigration processes. "Review of Trafficking Investigation" might suggest a specific investigative process related to human trafficking but lacks the connection to the broader immigration proceedings that "Referral to ICE" embodies. Thus, RTI as "Referral to ICE" highlights a critical step in processing immigration cases that necessitate further scrutiny or enforcement action by ICE.
