Swiss voters are heading to the polls to decide on a contentious immigration cap initiative. The proposal arrives as the country's national football team fields a lineup celebrated for its diversity, with players from immigrant backgrounds.

The initiative would impose strict limits on immigration, a polarizing issue in a nation where nearly a quarter of residents are foreign-born. Its timing alongside the World Cup has amplified debate about national identity and inclusivity.

Proponents argue the cap is necessary to preserve social cohesion and manage infrastructure strain. Critics counter that it contradicts Switzerland's tradition of openness and ignores the contributions of immigrants to the economy and culture.

The outcome remains uncertain, with polls showing a deeply divided electorate. A close vote is expected, with passionate campaigns on both sides mobilizing voters.
