Tensions are escalating across California ahead of Iran’s World Cup opener at SoFi Stadium, with protests outside stadiums, a legal fight over flags and heightened security.

At the center of controversy is a plan by some in the Iranian-American community to bring the historic Lion and Sun banner into the game.

It comes as a small protest took place in Los Angeles ahead of the match, while the Iranian soccer players were quietly flown into the city a day earlier than expected.

Supporters say they intend to display the symbol inside the venue despite reported restrictions. The dispute has already moved into court.

The Institute for Voices of Liberty has filed for a temporary restraining order in California Superior Court against FIFA, challenging what it describes as restrictions on the Lion and Sun flag at World Cup events.

The group argues FIFA is wrongly treating the emblem as a political symbol.

It says the Lion and Sun is a centuries old cultural icon tied to Iranian identity long before the current government, and for many in the diaspora it represents heritage and calls for a freer Iran.

In its filing, the organization is asking the court to protect free expression, clarify what counts as a political symbol under FIFA rules, and block enforcement of any ban across World Cup venues in California and beyond.

The group also said it attempted to raise concerns with FIFA before going to court but did not receive meaningful responses.

In a written statement included in the filing, iVOL said: “FIFA claims to celebrate unity and human rights, yet by banning the historic flag of the Iranian people, they are inadvertently shielding a tyrannical regime from peaceful dissent.

“We are asking the court to ensure that peaceful fans are not silenced, harassed, or stripped of their cultural identity during the world’s greatest sporting event.”

But while the legal battle continues, the most immediate tension is playing out in the streets and stadiums.

On Saturday, Iranian-American supporters attended the Qatar vs Switzerland match at Levi’s Stadium in the Bay Area, where some displayed Lion and Sun flags and “Free Iran” banners.

Activist and journalist Shayan Khosravani Farahani described the scene inside the venue

“When you enter the stadium, there is basically no special checking. There is only a metal detector, and nobody really pays attention when you go in.”

He also noted how enforcement tends to shift once inside.

“The only issue is once you are inside the stadium and displaying flags. You should not stand up and block the view of the people behind you, causing others to complain.”

He added that crowd dynamics can affect enforcement. If everyone around your section is Iranian, then there is usually no problem.”

Separately, organized protests were held outside SoFi Stadium in Los Angeles on the same day Iran’s national team was preparing for its World Cup appearance.

Members of the Iranian American diaspora gathered in coordinated demonstrations aimed at the Iranian government.

On the team side, Iran’s national squad also arrived in LA earlier than expected. The players flew into LAX from their base camp in Tijuana, Mexico, landing around 4:11 p.m. ET.
