Supporters could end up banged up in detention centers if they cannot prove they are in the US legally and may miss the football, Government officials have warned.

World Cup fans have been told to carry their passports at all times in case they get stopped by Donald Trump's ICE agents.

Three Lions and Scotland fans are about to jet to the US to see their heroes in action at the tournament which kicks off this week.

The UK’s Foreign and Commonwealth Office has advised supporters to carry their passports to prove they are in the country legally. It will carry an entry stamp from US immigration officials showing when they arrived in America and how long they can stay.

There have been numerous reports of Trump's US Immigration and Customs Enforcement - aka ICE - agents arresting tourists in recent months. The UK government states on its World Cup advice page: “Always carry a passport showing you have permission to enter or remain in the US.”

Fans travelling to the World Cup in Mexico have been told to leave designer clobber and flashy watches at home. They have also been warned about spiked drinks, corrupt cops and scams.

England play group games in the US but could travel over the border for a play-off match if they win their group. Other UK fans will journey there to watch non-home nation matches as it is a cheaper alternative to the US and Canada.

The Foreign and Commonwealth Office has issued a raft of sobering warnings to fans travelling to the nation.

Civil servants warned: “Do not leave food and drinks unattended in bars and restaurants. Criminals have robbed or assaulted travelers after drugging them.

“Tainted alcohol has caused illness or blackouts. If you have any concern get advice from your tour operator or the local authorities.

“There have been deaths and cases of serious illness caused by alcoholic drinks containing methanol in Mexico.”

Supporters have also been warned about dodgy cops - both genuine and bogus.

The travel advice continued: “Be wary of criminals posing as police officers and trying to fine or arrest you for no reason. They have targeted travelers driving rental cars.

“Some genuine police officers have extorted money from tourists for alleged minor offences or traffic violations.”

Pickpockets are also rife.

The government added: “Pickpocketing and theft are common, including on public transport.

“You should avoid wearing expensive-looking clothing, jewellery or watches, limit the amount of cash or credit and debit cards you carry, watch your luggage even in apparently secure places like the lobby of your hotel.”

Fans should also take care at cash machines,

The Foreign Office said: “Take care withdrawing money from ATMs or using exchange offices.

“Criminals have targeted people using these services. It’s generally safer to use ATMs during daylight hours inside shops or malls."
