What type of subject does the term "Present without admission" refer to?

The term "Present without admission" specifically refers to individuals who are physically in the United States but have not been granted entry by an immigration official. This situation typically involves illegal aliens who may have entered the country without going through the proper legal channels or who overstayed their permitted time. They are present within the jurisdiction but do not have the legal status to be in the country, which necessitates further action by immigration authorities.

In the context of the other types of subjects, refugees are individuals given protection due to persecution in their home countries; visitors are typically granted temporary visas for travel; and citizens have legal rights to reside in the country without needing further authorization. Each group has different legal statuses and definitions under immigration law, making it clear why the term "present without admission" is associated specifically with illegal aliens.
