Which of the following is an expedited removal situation?

Expedited removal is a process that allows immigration authorities to quickly remove individuals who are found to be inadmissible under certain circumstances. The situation where an individual crosses the border without authorization is classified as one of these expedited removal circumstances.

This process is designed to promptly deal with individuals who have not entered the country lawfully, which aligns with the definition of expedited removal. When someone is caught attempting to enter the U.S. without proper documentation, immigration officials can expedite their removal without going through the longer standard removal proceedings.

Other options represent scenarios that typically do not fall under expedited removal procedures. For example, an individual applying for asylum is actively seeking protection from persecution and would normally go through a different set of processes allowing them a chance to present their case. Similarly, a tourist overstaying a visa or an applicant for a green card may face removal but would not be subject to expedited removal in the same manner as someone crossing unlawfully at the border.
