Polish police and Border Guard units mounted a two-day “Operation Foreigner” on 2–3 March, the results of which were announced on 5 March 2026. Officers checked nearly 1 800 locations across the country, identifying 1 944 people and detaining 147 foreigners wanted by law-enforcement bodies – including 91 Ukrainian nationals – for offences ranging from visa overstays to Interpol red-notice warrants. Interior Minister Marcin Kierwiński said the sweep demonstrates Poland’s determination to keep migration “orderly and lawful” as special wartime flexibilities for Ukrainians wind down. Besides overstay cases, 20-plus individuals were held on national-security grounds and 130 return-orders were initiated.

For individuals and employers who need to stay ahead of Poland’s fast-evolving immigration rules, VisaHQ can be a crucial ally. The platform (https://www.visahq.com/poland/) offers real-time visa guidance, document checklists, and application assistance, helping applicants avoid the kinds of paperwork lapses that triggered many of the detentions during “Operation Foreigner.”
More than 26 000 police officers and 700 border-guard personnel took part, making it the largest interior-security action so far in 2026. For companies employing third-country nationals, the signal is clear: documentation lapses will increasingly lead to detention and deportation rather than warnings. Immigration advisers report a spike in site visits to dormitories and factories, and recommend maintaining hard copies of residence cards on-site, ensuring addresses in the foreigners’ register (PESEL) are up to date, and budgeting for legal counsel in case of audits. Ukrainian community leaders have appealed for clearer communication, noting that many of the detained worked informally while awaiting residence-permit slots that can take months to secure. Officials replied that future sweeps are likely as Poland transitions to standardised rules, urging migrants to regularise quickly.
