NEWARK — It was barely past noon on Friday, and the Ironbound neighborhood in Newark was already a sea of red and white jerseys. Lines stretched down Ferry Street to get into Iberia, Mompou and other Portuguese restaurants. Red, green and gold garland draped across telephone poles. Portuguese songs blared from an open-air bar.

It was game time — Portugal vs. Spain in a World Cup first-round match — and all work in the thriving Portuguese enclave essentially stopped.

Among those focused on nothing but the game were the prime minister of Portugal, António Costa, who came to United States for a celebration of Portuguese culture, and the governor of New Jersey, Philip D. Murphy, who took a brief break from a budget standoff.

“The budget does take priority, let there be no doubt about it,” Mr. Murphy said, adding that he remained confident that a budget deal would be made in time for the end of the World Cup. “I still remain optimistic that you’ll be watching soccer on June 30.”
