*In collaboration with Ana da Silva Ferreira In Portuguese football, the transfer window is a high-tension sprint: 33 days between the beginning of January and February to reinforce squads, sign up talent and compete in European competitions. But a sprint that can stumble at the airport border, where the Public Security Police can transform a signed contract into a return ticket. It happened a few days ago: a professional athlete, with a link to a sports society participating in professional competitions, an employment contract, a term of responsibility from the employer and proven means of subsistence, was refused entry to Lisbon for declaring his intention to work without an adequate visa. Liga Portugal, aware of the imminent risk in this winter window, warned the clubs in a memorandum that exposes the systemic fracture post-SEF. The extinction of the Foreigners and Borders Service by Decree-Law No. 41/2023, of June 2nd, divided responsibilities: the Foreigners and Borders Unit (UNEF) of the Public Security Police was responsible for border control (Law No. 55-C/2025, of July 22nd); to AIMA, the residence permits. The Protocol signed on July 24, 2024 - between AIMA, the Borders and Foreigners Coordination Unit, the Portuguese Professional Football League and the Portuguese Football Federation (among other signatory sports federations), - aimed to speed up the residence permit for professional athletes from the I and II Leagues who legally enter national territory (visa exemption, short stay or tourism), in the previous month or during the registration windows, through a contract and liability agreement signed by the contracting sports company. But here's the rub: the PSP interpreted that the employment declaration upon arrival invalidates the visa exemption, requiring a long-term permit to “reside/work”. The PSP's understanding was that the protocol speeds up post-entry; does not authorize entry when the border agent comes with professional intent. Stopwatch against bureaucracy A work visa can take up to two months to be issued. Such a period appears to be highly incompatible with a transfer window, whose duration varies between approximately one month in the winter market and two months in the summer market. The winter window, less than five weeks long, is thus a match lit in a puddle of administrative gasoline. Non-EU nationals face saturated consulates; Community members (EU/EEA), visa-free, risk the same fate when confessing the contract to passport control. Furthermore, FIFA is unequivocal in establishing that any employment contract concluded with a player cannot be conditioned on obtaining a work visa. Therefore, any obligations assumed by clubs that may be refused or temporarily made unfeasible for reasons related to the granting of the aforementioned visa must still be fully complied with. Green corridor now Professional football demands the consecration of an exceptional regime of a rapid nature, appropriate to its economic specificity and the inherent sporting calendars, in alignment with its recognized relevance on the economic and international level of Portugal. There is an urgent need to create a truly integrated “sports corridor” compatible with the reality of professional football. The solution could involve creating a digital platform shared between the League, FPF and AIMA, allowing the simultaneous submission of an employment contract and term of responsibility for issuing a provisional visa in just 72 hours or creating a special visa and a fast-track consular, adapted to the professional reality of the I and II Leagues, similar to the accelerated regimes already existing for strategic sectors such as culture and scientific research. Without a specific regulatory change, clubs risk remaining hostage to administrative interpretations and legal limitations that hinder decisions and compromise sports planning. Professional football exports talent, animates stadiums and fills tax coffers. The European Union recognizes sport as a “general interest” (TFEU Treaty, art. 165), justifying migratory exceptions. As long as Portugal does not align its entry policy with the competitive dynamics of its football, it will continue to waste talent at the boarding gate - defeated not by tactics, but by the fact that it never arrived.
