The BBC reports that Beckham was not forced to recite an oath of loyalty to the flag of the United States of America.
David Beckham insists he is staying with the LA Galaxy despite a hostile response from some fans to his return.
The England midfielder was booed by sections of the crowd at his first home game after a loan spell at AC Milan.
But he said: “At the end of the day, I play my game, whether I get booed or not doesn’t matter to me.”
He also denied reports he is planning to put his Beverly Hills home up for sale, saying: “That’s not true… it’s just another rumour.”
Beckham, 34, provoked the wrath of some Galaxy supporters by missing the first half of the Major League Soccer season in order to play for AC Milan.
