The word 'undocumented' is used to describe someone who does not have the proper legal documents to be in a particular country. This refers to immigrants or foreigners who may have entered the country illegally or overstayed their visa. It is important to use this word instead of 'illegal' or 'illegal immigrant' as it respects their human dignity and acknowledges their lack of official documents, without labeling them as criminals.
