The term 'Entrance Requirement' refers to the qualifications or conditions that must be met in order to gain entry into a certain place or program. In this case, two of the solutions are 'VISA' and 'CUE'. A VISA is a document issued by a government that allows a person to enter, remain in, or leave a country. A CUE is a signal or indication that prompts someone to do something. Therefore, the Entrance Requirement for a certain place or program could include having a valid VISA and/or following certain CUEs.
