An unauthorised arrival is a person who has arrived in a country of which they are not a citizen and does not have a valid visa or does not satisfy other required conditions for entry to that country.
A person may be described as an unauthorised arrival when they have crossed a national border with the intention of applying for refugee status, in which case they may be described as an asylum seeker.
Under the United Nations Convention Relating to the Status of Refugees, a person has the right to cross national borders if they are seeking asylum from political repression or various other forms of persecution.
