Since Brexit, British residents have been able to visit the Schengen Zone for 90 out of every 180 days without a visa.
Residents of Gibraltar who regularly travel into Spain for work reasons or to see friends have faced queues and delays.
Claudia Gualdi, travel intelligence data lead at Riskline, spoke to Express.co.uk to explain how Brexit has impacted residents and what might help ease the queues.
She said: “The prolonged debate around passport controls at the Gibraltar/Spain frontier has become a challenge for Gibraltans and Britons alike.
“Gibraltar passport holders are less likely to be stopped at border crossings with Spain. But Spanish border officials frequently require UK passport holders, including those with Gibraltan residency cards, to submit additional documents.
“These may include proof of a fully paid hotel booking with no cancellation fee, a valid reason for the visit, a return flight ticket and evidence of sufficient funds to cover the stay and departure from the country.
“Yet, these entry requirements are not so clear and not so regularly enforced, but they reportedly cause daily queues and delays.”
British tourists may be asked to prove they have enough money for their stay when they cross the border into Spain.
They can also be asked for the address they’re staying at although this won’t always be the case.
The British Government also warns tourists and residents that there is no fee to enter or leave Gibraltar and they should not hand over money to anyone claiming there is a charge.
Claudia added: “Negotiations between the EU and the UK on the post-Brexit relationship of Gibraltar with Europe are ongoing.”
The travel expert believes that the implementation of new technology at the border could help to ease some of the issues.
From the middle of 2025, British tourists may need to have an ETIAS visa to travel to the EU.
This will cost a small fee to obtain and will be required by non-EU citizens to travel to the Schengen Zone.
