An increasing number of foreigners are arriving in Portugal irregularly, mainly using trains and buses as means of transport. Many of these travelers come from other European countries, which suggests established routes within the European space.
Some of these foreigners have been in an irregular situation for several months, indicating that the phenomenon is not occasional but rather a continued reality. This suggests that there are support networks or mechanisms that allow prolonged stays even without regular documentation.
The cities of Lisbon and Porto are the main areas of focus for the Public Security Police (PSP), which maintains reinforced surveillance in these zones. The choice of these cities as monitoring focal points suggests that they are entry points or areas of concentration for these irregular migratory flows.
