The Spanish royal palace announced that King Felipe VI, Queen Letizia, and their daughters, Princess Leonor and Princess Sofia, will travel to New Jersey on Sunday to attend the national team's World Cup final match.
Spain will face Argentina after defeating France 2-0 in Tuesday's semi-final in Texas to move a step closer to a second World Cup title.
King Felipe had travelled to Mexico in June to watch Spain defeat Uruguay 1-0 in the group stage, cementing an improvement in relations between the two countries after years of tensions.
Spain secured a spot in the World Cup final with a 2-0 semifinal victory over France on Tuesday in Arlington, Texas, setting up a deciding match against either Argentina.
France entered the semifinal highly regarded following strong offensive performances throughout the tournament in the United States, but the French squad was unable to overcome the Spanish team.
Mikel Oyarzabal opened the scoring for Spain with a first-half penalty, and Pedro Porro doubled the lead in the second half. Despite offensive adjustments, the two-time champions were unable to score.
Following the match, Spain coach Luis de la Fuente attributed the success to a consistent tactical approach developed over nearly four years, commending his players' dedication, teamwork, and execution.
The game at the AT&T Stadium caught fire midway through the first half when Salvadoran referee Ivan Barton pointed to the penalty spot after a reckless challenge by France left-back Lucas Digne on Spain winger Lamine Yamal.
Oyarzabal hammered the ball past France goalkeeper Mike Maignan for his fifth goal of the World Cup to leave France trailing for the first time in the tournament.
It was the Real Sociedad forward's 18th goal in his past 20 games for Spain. Deschamps threw on Desire Doue for Bradley Barcola in the 57th minute in a bid to supercharge his attack but a minute later they were 2-0 down after a stunning team goal for Spain involving Dani Olmo and defender Porro.
Spain, who have conceded just once in the entire tournament, are the first team in World Cup history to keep six clean sheets at a single edition. They have now gone 37 games without defeat in all competitions, equalling the record unbeaten streak by a European nation.
